Xin Fan - CFO
Thank you, Juliet. And thank you, everyone, for participating in our 2022 Fourth Quarter and Fiscal Year Financial and Operating Results Conference Call. I'm pleased to deliver today's opening remarks on behalf of Mr. Chen.
In 2022, we proactively adjusted our strategies and reprioritized ours goal to better align ourselves with the new industry paradigm. Specifically, we placed our focus on DAU growth and how to reach profitability.
Digging into our progress on these 2 fronts. First, our users and their daily engagement with our community remain the foundation of our business. By focusing on DAU growth, we are bringing higher-quality users to our platform, which ties in more closely to our monetization potential.
In Q4, our DAUs increased to 93 million, up 29% year-on-year. This brought our DAU to MAU ratio to 28%, a meaningful improvement from 26% in the same period last year. The average daily time spent per user on our platform reached 96 minutes, driving the total time spent on our platform, up by 51% year-on-year. We will continue to cultivate our DAUs with optimized product offerings and algorithms and further support our commercial prospects with controlled sales and marketing spending.
Second, we improved our commercialization efficiency and elevated our cost-reduction measures to bring us closer to our goal of profitability. Our total net revenues for 2022 were RMB 21.9 billion, and the total net revenues for Q4 were RMB 6.1 billion, up 6% year-on-year. Our gross margin improved to 20% in Q4 compared with 18% in the previous quarter.
We continue to take measures to control our expenses and improve our organization efficiency. Specifically, in the first quarter, we cut sales and marketing expenses by 28% year-on-year. Sales and marketing expenses as a percentage of total net revenues reduced from 30% in the same period last year to 21% in the fourth quarter. We have also streamlined our personnel and trimmed our noncore and underperforming business. As a result, our non-GAAP net loss in the first quarter narrowed by 21% year-on-year and 26% quarter-on-quarter.
As we move through 2023, our operational goal is to become a more efficient company. We will centralize our resources to focus on less but more important tasks. Specifically, we plan to continue to grow our DAUs, improving our gross margin and tightening our expenses. And we are executing on these actions. We believe we are on the right track to achieve our breakeven target by 2024.
With that overview of our strategic approach and progress, I'd now like to provide a brief update on our 3 core pillars of content, community and commercialization.
Starting with content. Our ever-growing content ecosystem is our most valuable asset. In the fourth quarter, our platform hosted 3.8 million content creators, 25% more than the same period a year ago. Creators submit 17.6 million videos, up 62% year-on-year, both on a monthly basis.
To encourage more users to turn their ideas into creation, we will provide them with more easy-to-use tools to get would-be creators started. At the same time, more traffic will be led towards mid- and long-tail creators. Our goal is to turn more users into creators, driving both our content offerings and user engagement.
Expanded content scenarios are also attracting more traffic to Bilibili. For the fourth quarter, total daily videos views were up 77% year-on-year to 3.9 billion. In particular, Story Mode daily video views increased by 175% year-on-year while PUGV video views increased by 56% in the first quarter. Story Mode has allowed us to expand into the vertical video market, bolstering our DAUs, increasing user time spent on our platform and opening more commercial opportunities for us to pursue.
To unlock our commercial potential, in 2022, we further integrated our commercial channels within our content ecosystem. The combination has created more immersive advertising opportunities and the various monetization channels for content creators. Over 1.3 million content creators earn income-ed through multiple channels on Bilibili in Q4, up 64% year-over-year.
Looking at our community. Our inclusive community environment and the [raise] interaction tools are creating tighter bonds between our users and our platform. In the fourth quarter, user's average daily time spend on Bilibili reached 96 minutes. Monthly interactions also increased by 35% year-on-year to 13.6 billion. And for the core members of our community, the number of official members reached 195 million in the fourth quarter, up 34% year-on-year, and their 12-month retention rate continued to exceed 80%.
Now let's review our commercialization progress and how we think about it moving forward. For the fourth quarter, our total net revenues reached RMB 6.1 billion, up 6% year-over-year, and our full year revenue grew by 13% to RMB 21.9 billion. We are now more focused on improving our commercialization efficiency and specifically on improving our gross margin at the company level.
Now I'd like to share more color on each of our commercial business lines. First, our VAS business. Revenues from VAS was RMB 2.3 billion for the fourth quarter and RMB 8.7 billion for the year, up 24% and 26% year-on-year, respectively. Live broadcasting in particular has shown solid growth. For 2022, revenues from live broadcasting increased by over 30%.
Our strategy to integrate live broadcasting within our video ecosystem has prompted more creators to tap into live broadcasting universe. This has helped to penetrate more video users, converting paying users and optimize our revenue-sharing structure organically. In the fourth quarter, the number of monthly active live broadcasting hosts increased by over 70% and MPUs for live broadcasting grew by over 40%, both on a year-on-year basis.
Looking ahead, live broadcasting will continue to be one of our primary revenue growth drivers. We expect to optimize our revenue-sharing ratio and further improve live broadcasting gross margin. By the end of the fourth quarter, we had added nearly 1 million premium members from the prior period, reaching a total of 21.4 million premium memberships.
We launched multiple Chinese anime titles during the period, including the highly anticipated sci-fi thriller, The Three-Body Problem. In January 2023, our co-produced traditional Chinese style graphic anime, Yao-Chinese Folktale, Zhongguo Qi Tan, become a smash hit, generating over 200 million video views on our platform.
As for our advertising arm. We continue to gain market share in 2022. Advertising revenues were up by 12%, reached RMB 5.1 billion in 2022 and RMB 1.5 billion in Q4. Our top-performing verticals in the first quarter were mobile games, e-commerce, digital products and home appliances, automotive and skin care and cosmetics. In 2022, we'll further open up our ecosystem to embrace more advertising opportunities across various video viewing scenarios.
The newest scenarios we introduced in Story Mode and improved sales conversion modules has proven our success in performance-based ads and carry higher ROIs. In the fourth quarter, our performance-based ad revenue grew by over 50% year-on-year. In addition, as our users getting mature and into new life stages, their new consumption needs, such as automotive and home appliance, also attract more advertisers, and their ad budgets have been allocated to our platform.
Moving into 2023. We will continue to invest in and improve our ad infrastructure and further integrate our ad capabilities within our content ecosystems.
Turning into games. Revenues for the year were RMB 5 billion and RMB 1.1 billion for the fourth quarter. We are committed to the strategy of development in-house, distribute globally. In Q4, we restructured our game development to effectively align with this goal. Specifically, we eliminate underperforming self-developed projects and centralized our resources to focus on genres where we are already experts.
In 2022, our self-development games contributed 5% of our total game revenues. We expect this ratio will continue to expand in 2023 as we roll out more self-development games.
Looking at our pipeline. We are planning to launch 2 self-development games, [Soldier] and [Elysia], as well as 6 exclusively licensed titles, in the second quarter of this year. As game license approvals have gradually resumed in China, we expect to engage in more opportunities in the domestic market.
In summary, the new industry dynamics call for more efficient operations. In 2023, we will continue to centralize our resources to grow our DAUs, increase our gross margin and narrow our losses. Throughout this process, we will continue to strengthen our execution and tighten our spending while selectively investing R&D, will improve our commercialization efficiency.
With these measures in place, we believe we are on the right track to reach our financial goals and become a stronger, more resilient and efficient organization. This concludes Mr. Chen's remarks.
I will now provide a brief overview of our financial results for the fourth quarter of 2022 and outlook for the fiscal year of 2023. For a review of our fiscal year 2022 results, please see our press release issued earlier today.
Total net revenues for the fourth quarter were RMB 6.1 billion, up 6% from the same period of 2021. Our total net revenues breakdown by revenue streams were approximately 38% VAS, 25% advertising, 19% mobile games and 18% for our e-commerce and other business.
Cost of revenues increased by 4% year-over-year to RMB 4.9 billion. Our gross profit in the first quarter were RMB 1.2 billion, and our gross margin was 20.3%, up 2.1 percentage points sequentially. With our tightly controlled cost structure, we expect to show continued margin improvement throughout 2023.
Total operating expenses were RMB 3.6 billion, up 15% from the same period in 2021. As we work on increasing our commercial prospects, we are also keeping a lean cost structure. We cut sales and marketing expenses in Q4 by 28% year-on-year to RMB 1.3 billion, while DAU grew by 29% year-over-year. Sales and marketing expenses as a percentage of total revenues was also down to 21% compared to 30% in the same period last year. We will continue to control our sales and marketing expenses while delivering solid DAU growth in 2023.
G&A expenses were RMB 870 million, up 52% year-over-year. The increase was primarily due to the one-off severance pay of RMB 252 million related to our organizational restructuring.
R&D expenses was RMB 1.5 billion, representing an 87% increase year-over-year, which was primarily due to increased R&D personnel and a one-off consolidation cost of RMB 470 million related to our certain game projects.
As we move through 2023, we will take additional actions to reduce our operational expenses. We think our overall operating expenses peaked in 2022 and will start to decline in 2023.
Net loss and adjusted net loss was RMB 1.5 billion and RMB 1.3 billion, narrowing by 29% and 21% year-on-year, respectively. Our net loss ratio in the fourth quarter was 24%, a very notable improvement from 36% for the same period a year ago. We expect to continue to narrow our losses in 2023.
Turning to our capital allocation and liability management. we are keenly aware of our cash reserves and have taken steps to improve our balance sheet, which gives us the flexibility we need to reach our breakeven target by 2024. We are actively managing our liabilities and to improve our balance sheet.
In the fourth quarter, we repurchased and retired a total principal amount of USD 547 million notes for a total cash consideration of USD 420 million. As a part of our liability management plan, in January 2023, we completed USD 409 million equity offerings and note exchange program. We retired a principal amount of USD 385 million of convertible notes for a consideration of USD 331 million cash funded by this offering. The remaining USD 69 million in proceeds were used to replenish our cash reserves. After these transactions, we currently have 3 outstanding CBs that totaled USD 1.6 billion.
As of December 31, 2022, we had a cash and cash equivalents, time deposits and short-term investments of RMB 19.6 billion or USD 2.8 billion. We believe this amount is sufficient to cover all of our remaining convertible bonds and fund our future operations while we take further action to narrow our losses and reach non-GAAP breakeven by 2024. With that in mind, we are currently projecting net revenues for the full year of 2023 to be between RMB 24 billion and RMB 26 billion.
Thank you for your attention. We would now like to open the call to your questions. Operator, please go ahead.

[Interpreted] Starting from last year, we've noticed that the Internet industry has entered into a new era. Every company is more focused on the quality of the growth, the quality of revenue as well as improving gross margin and focus on cash flow.

Rui Chen - Chairman of the Board & CEO

[Interpreted] Overall, our business will be more focused. There will be 2 important tasks. One is to increase our top line and narrow our loss. Number two is to increase our DAU.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] Number one task, increase our top line. When I say increase our top line, I'm referring to the increase of top line as well as our gross profit. We'll be focusing on improving our gross margin and narrowing our losses.
In the fourth quarter, we've achieved gross margin improvement from a year-over-year and quarter-over-quarter basis. We also narrowed our net loss by 29% year-over-year. We expect that, in 2023, our overall net loss will narrow more meaningfully and to achieve our breakeven target by 2024.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] On the user aspect, we will no longer just pursue the absolute number of MAU, but rather to focus on the growth of our DAU, as well as the sales conversion of each DAU that can bring to the company.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] In 2023, we are expecting our DAU-to-MAU ratio will continue to improve. Currently, we're at 28%. We expect to increase to 30% level.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] This will mean better engagement, better stickiness of our company as well as higher commercialization potential.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] I still want to emphasize that our community and content ecosystem is the cornerstone of our business. No matter what kind of strategy, the community and the content ecosystem is the foundation of the business.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] In this year, we'll be celebrating our 14th anniversary. And in the past 14 years, we have experienced 3 industry cycle, which is the mobile PC era, mobile era, and as we're going through the AI-powered era. No matter how the technology industry is evolving, for Bilibili, the community and the PUGV content ecosystem aspect is what has kept us going while others come and go.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] We believe the value of high-quality content. We also believe in the value of the high-talented content creator can bring. That is the biggest moat for our business. It is also the biggest competitive advantage that we own in this ever-changing landscape.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] We believe in that our unique content ecosystem can continuously generate high-quality content and talented content creator. And the value of this content that bring to Bilibili is our core competitiveness. We'll continue to cultivate that and continue to build on that and bring high-quality growth to our company.
Operator
Next question comes from the line of Xueqing Zhang from CICC.
Xueqing Zhang - Analyst
(foreign language) My question in regards to financial outlook. As Rui mentioned before, we see the company's gross margin has continued to increase in the past few quarters. So how does management think about the trend of margin in 2023? And since we view the full year revenue guidance, what's the growth of each segment does it imply? And lastly, on the bottom line, what's the outlook for the net loss narrowing in detail?
Xin Fan - CFO
Yes, this is Sam. I will take your question. As Mr. Chen mentioned, the key objective of the company for this year is to improve our gross margin and narrow our loss. So that's why for 2023 revenue guidance, we are cutting down low-margin business, such as e-sports content, [licensing] revenue business and certain low-margin e-commerce business.
As a result, we expect our e-commerce and other revenue line for 2023 to decline by mid 20% to 30%. However, we expect the gross margin and the gross profit for e-commerce and other business to improve year-over-year. And for the non-e-commerce business revenue, including our games, VAS and advertising, if we combine these together, we still expect to grow by 20%-plus year-over-year in 2023.
And in regarding to the gross profit. Overall, the increase of the revenue will drive the increase of the gross margin, especially for certain fixed costs, such as server and bandwidth, staff costs and content costs. In 2023, as I mentioned, we will be more selective and ROI-focused in terms of the content investment. We also expect the percentage of the server and bandwidth cost start to decline.
In terms of the revenue-sharing costs, we expect each business line's gross margin will improve year-over-year. As high-margin business gradually increase their contribution, there will be more meaningful improvement on revenue-sharing cost.
For OpEx, total OpEx had peaked in 2022. We expect OpEx will start to decline in 2023. We cut sales and marketing expenses by 15% in 2022. We expect further cost cuts down for sales and marketing in 2023. Meanwhile, G&A and R&D expenses in terms of the absolute dollar amount will also decline slightly in 2023. We expect our gross margin to gradually improve to mid 20s throughout 2023, and we also expect meaningfully narrowed our non-GAAP operating loss in 2023.
Operator
The next question comes from the line of Yiwen Zhang from China Renaissance.
Yiwen Zhang - Research Analyst
(foreign language) So my question is on the advertisement. Can you discuss about the outlook of ad market in 2023? And what kind of change are we seeing?
And secondly, on the product side, can you give us the latest update on the Story Mode? And what kind of development should we expect on our ad business on the product side?
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] Firstly, on the Story Mode, our multiscreen and multi-scenario is one of our key strategy that's driving Bilibili's user growth. The 28% DAU-to-MAU ratio and 96 minutes daily user time spend means the strategy is working effectively.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] Story Mode as a newly added scenario is an important supplement to our existing PUGV, OGV, like broadcasting and big screen OTT scenario. We noticed that since the launch of Story Mode, it has played a vital role in terms of increasing user engagement, especially for users who are not as active. It has also helped us to attract new content creators across the video industry. At the same time, it has driven better-than-expected increase in terms of video views as well as user time spend. Story Mode has essentially allowed users to access their favorite Bilibili content anytime, anywhere.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] Bilibili has always put high quality content and content creator at top priority. Since inception, PUGV ecosystem has maintained a very healthy growth. When we are mentioning the store mode grow at a fast pace, don't forget that PUGV also grew by 50% year-on-year and maintained a very healthy growth rate.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] Whether as creator or content consumer, their need for high-quality content will evolve, so will their sense of style. We think that Story Mode has served a very good vessel to carry PUGV content to support our ever-growing ecosystem. In addition, the combination of Story Mode traffic and our existing ecosystem has helped us to increase our ad efficiency, and this has also brought new commercial opportunity for live broadcasting and advertising.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] As you may already aware, it has been a very challenging market for advertising in 2022. The overall ad market only had low single-digit growth. And under this challenging market, we are continuing to gain market share. For Bilibili's full year advertising revenue, we have reached RMB 5 billion.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] As for 2023, there has been a recovery of confidence for advertisers. Maybe overall industry can achieve a double-digit growth, we will see that. However, we also noticed that for all advertisers, they will be more conscious and we'll be focusing more on the core value of their ads investment and their ads investment efficiency.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] The key reason for advertisers to invest in ads, we have categorized for 3 main areas. One is new product launch, number two is brand rejuvenation, number three is continuously to increase their brand perception and drive sales conversion. The advantage for Bilibili advertising is that we can cover all above 3 core needs, and we are confident our ads growth rate will beat the industry growth rate.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] In 2023, we will be looking to upgrade our sales model for different industry verticals. We believe the integrated marketing will continue to be our long-term growth driver. For our leading industry verticals, we'll continue to build high barriers and upgrade full ad product matrix, such as for games, 3C and digital product.
Take games for an example. Bilibili has the largest gamer and game content community in China, and with near-90 million unique users consume content, game content, on a monthly basis. We think the recent regularization of [bang hao] is also a favorable tailwind for us.
In Q1, we have unified the OKRs for 3 key game teams, including game distribution, game ads and game content in order to provide a more comprehensive service to game companies and improve the efficiency for game distribution. Our goal is to enable every game company to reach their target audiences in time and also achieve long operation cycle and higher conversion rate on Bilibili.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] Secondly, we expect to further gain market share and attract larger budget from areas like e-commerce, automotive and general FMCGs.
Take e-commerce, for example. Bilibili is --
Hello? Hello, operator?
Operator
Please carry on.
Juliet Yang - Executive Director of IR
Yes, we were disconnected for a second.
We were saying that Bilibili is the only video community who is open about e-commerce collaboration. Last year, together with Alibaba, Pinduoduo and JD, we have optimized our brand-feeding conversion model on top of our traditional brand and performance ads. In 2022, over 1,000 new brands and over 10,000 SKUs have debuted on Bilibili through (foreign language) function, which also recorded better-than-expected performance-based ads revenue.
We will continue to integrate video and e-commerce -- live broadcasting e-commerce system and explore Bilibili's unique open loop transaction model. We also expect to quickly expand our market share in e-commerce ads and their budgets this year.
Ni Li - Vice Chairman of the Board of Directors & COO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] On top of all that, we are also working to improve our algorithm infrastructure and invest in AIGC application and also improve our data capacity to provide our customers with more scientific marketing data point. Also, we'll continue to explore more ad scenario, [intense] ad-friendly atmosphere in our community. All of which are the right thing to do, and we have -- that's what we have done in 2022 and will continue to carry into 2023.
Operator
Our next question comes from the line of Lei Zhang from Bank of America Merrill Lynch.
Lei Zhang - VP in Equity Research & Research Analyst
(foreign language) My question is mainly about your game business. Can you share with us your in-house game strategy and outlook? And any new game we can expect after the resume of game licensing?
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] We have entered a new era for game business last year. [bang hao] is one of the reasons. Another reason was the increasing penetration rate for mobile gamers in China. And also, gamers' evolving taste and their increasing demand for higher-quality games are also shaping the overall games industry. As production cost rises, the success rate for games is declining.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] In the era of lower gamer penetration rate, it's easy to make money for game company as long as they have good quality of titles. However, we believe in this new era, there will only be 2 kinds of games can make money and succeed. One is the super mega titles, number two would be the #1 title in a segment/genre because it will have a longer life cycle. And only the two kinds of games will be able to gain market share and survive in this new era.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] Bilibili's game strategy is designed to serve the market -- the next market trend -- the market trend in the next few years. We will be firmly executing the strategy of develop in-house and distribute globally. This will be the must-to-dos for the next industry cycles because only global distribution can cover the increase in production cost, and only the highest quality of games have -- will have more operation cycle, hence, to achieve higher ROI.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] In terms of genre, we will be more focused. Whether it's a jointly operated game or our self-development game, we will be focused on the area that we hold the most advantage. The ACG card game will be one of the key game genres we'll be focusing on. And also, we'll be looking to cut down the number of projects we will be developing and focus our best resources on limited cost.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] But from a results perspective, the investment we made in self-development games is starting to bear fruit. In 2022, our self-development games revenue is already contributing about 5% of total game revenue. We expect this ratio will continue to increase in 2023.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] As for the [bang hao], we believe the releasing bang hao has already been normalized. There has been quite regular for domestic bang hao to be released on a monthly basis. We have also noticed that in the imported titles, there has also been a batch that's been approved. So we believe that this has been an industry tailwind favorable to Bilibili. Not only our self-developed games, it's also being -- it will also be favorable for our game jointly operation, as well as for our game advertising business.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] Also, we are looking to launch 2 self-development titles in the second quarter this year (technical difficulty)
Operator
Please remain on the line. Your conference will resume shortly.
(technical difficulty)
Juliet Yang - Executive Director of IR
Hello? Operator, next question, please. Can you hear me?
Operator
Our next question comes from Lincoln Kong from Goldman Sachs.
Lincoln Kong - Equity Analyst
(foreign language) So my question is about AIGC. So basically, this is a pretty hot theme for this year. Can management elaborate a bit more, how we think Bilibili can apply in the whole AIGC front? And the potential on the product and monetization opportunity?
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] I believe that the opportunity that AIGC can bring is a mega event, not only for the industry players, but for the whole society to pay attention. We believe it will bring a huge productivity increase in terms of content generation.
First, an analogy would be the invention of the mobile phone camera. It has allowed everyone to record video anytime, anywhere. And the AIGC can help to increase the productivity of those content and significantly lower the production cost.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] We believe it has brought a very big opportunity for Bilibili as well as for many other players in this industry. But especially so for Bilibili is because, for one, we are a massive content platform. Number two, we are a UGC platform.
Rui Chen - Chairman of the Board & CEO
(foreign language)
Juliet Yang - Executive Director of IR
[Interpreted] First aspect would be on the search front. The ChatGPT-similar experience will help users to find the video that they want more efficiently, such as product reviews.
Let's say people want to look for a new Airpods review. For Bilibili, who has our own data, we can easily accumulate and find and organize and structure the useful information and present to the user. And whether it's in the format of video clips or in the format of text, it will largely enhance the user experience when they use the search function.
Rui Chen - Chairman of the Board & CEO

[Interpreted] As for Bilibili, because we have a massive amount of knowledge-related content and knowledge content in a constructive way, it has more time value. Even after a few years back, we can still find that historical videos that continues to generate views and bring value to users. The ChatGPT-like search experience will help us to enlarge the value of our historical video content, at the same time, to improve the consumption efficiency for our users.

[Interpreted] In terms of content creation tools, we believe the AIGC can bring revolutionary experience that allow more users to start creating content. For example, the same material can be presented in different formats in different videos. And also allow many users, who used to just be content consumers, now they can easily create content like a professional.

[Interpreted] Lastly, on virtual content creators. As you may know, Bilibili is already currently the largest virtual content creator platform in China. We have tens of thousands virtual content creator, virtual live broadcasters on Bilibili. AIGC can bring more automatic and more efficiency, more -- higher user experience to the virtual characters.
For example, our virtual content host, Luo Tianyi, what AIGC can bring is transform her to a real person. And that will bring revolutionary experience for people who are a fan. And this is -- this has a massive imaginary space that what we can do with it. So we believe AIGC will serve very positive effects in terms of the virtual content creator, virtual live broadcasting host and the virtual idols that Bilibili can offer.

[Interpreted] As a platform who's connecting content creator with users, the evolution of production tool will serve very positive, bring very positive change to our platform. The change probably will be similar to the PC-to-mobile era. That's allowing more people to access the Internet, allow more users to be able to create content easily. And that's why our user has increased by tenfold in the past few years.
And I'm personally very looking forward to the evolvement of AIGC tool in terms of improving the video production efficiency, allowing more people to create content more easily that will definitely serve Bilibili as a content platform the most.
