Furthermore, we will optimize our marketing strategy to strengthen partnerships with game developers, coupled with our interactive gaming content community to enhance user engagement. In addition with the price level of corporate deployments gradually returning to a reasonable range, we believe that prudently purchasing some co-copyrighted tournaments will help us domain our own competitiveness in the industry. This investment will also foster the ecosystem of our game-centric community and enhance our core user engagement and retention rate, thereby facilitating the company's long-term development. Next, I'd like to share with you our business updates from the fourth quarter in more detail. For Q4, our average mobile MAUs for the quarter were 57.4 million, a slight sequential increase despite the year-over-year decline of 8 points. The main reason for the year-over-year and quarter-over-quarter MAU changes include: First, due to the implementation of our selective corporate procurement strategy in early 2022, we experienced a decline in all MAUs since the fourth quarter of the year. Nevertheless, in the fourth quarter, despite the negative impact on user traffic from the absence of the world -- of the LoL World Championship Tournament, our creative user campaigns and operations on existing copyright tournament events effectively attracted and engaged our core users. As a result, mobile MAUs on our platform achieved growth for the third consecutive quarter. Second, we continue to advance our innovative membership business, extending our game-specific membership services to broader game segment. By combined game features with users' needs, this initiative has gained traction among both new and existing users. Moving on to our content ecosystem. Capitalizing on the widespread popularity of eSports, we continue to sharpen our products and operations, including the consistent upgrades of our game content. Based on gaming features, we continuously created an even broader selection of more interactive and engaging premium content. On top of that, we built a healthy and vibrant interactive ecosystem for users through innovative services, providing them with the community-based platform and a novel membership business. These efforts cannot only ensure long-term retention by meeting certain gamers' needs for upgraded game content, but also increase overall user engagement and stickiness on our platform, that's driving user growth in the long run. In the fourth quarter, we continued to improve our diversified self-produced tournament system and organized more than 90 eSports tournaments. Leveraging our top-tier streamer resources, we focused on promoting IP content in partnership with star game streamers. In this effort, we created a series of premium gaming content combined with entertainment-oriented activities in our game segment, such as League of Legends and Honor of Kings. This content in general, coupled with the joining parties, has proven to increase users' motivation to engaging interaction and the line-up of our game communities, appealing to both new and existing users. Self-produced tournaments have become one of our main avenues to promote eSports popularity across the board. For example, based on Honor of Kings large gamer base, we housed Honor of Kings user cup national challenge. This competition opened enrollment to all Honor of Kings players and both its easy access to rewards and wider user participation. Specifically, we integrated the tournament's content with our user community. Users were able to enroll, participate and advancing rank within our community channel, while other users could take part in a series of fun activities such as [indiscernible] a single player competition and interactive reward. Combining game content with our user communities captivated mind-like gamers. And at the same time, it has tightened bonds with heavy users. As we improved our self-produced tournament system and further enhanced its value, we launched a series of eSports partner selection mechanism based on these tournaments. In the user cup mentioned earlier, we unveiled the eSports project. We've seen growth opportunities to discover high potential streamers and fortify user segment. In the fourth quarter, we launched all new eSports school team selection season for colleges. The competition covered three mainstream eSports games and attracted more than 2,000 college teams from 11 provinces, providing more college for spend with the platform to showcase their skills. It has also helped us to discover potential sports talent and enhanced stores appeal and brand influence among college and university. In terms of corporate detergents, we reinforce user engagement and stickiness to reach derivative content and diverse operation activities. In the Honor of Kings Champions Cup KIC, we added auxiliary functions such as home team support and watching reminder to further elevate our user experience. Moreover, the team, Wuhan.eStar, which we signed and invested in, maintained its excellent performance throughout the year and became the champion of the Champions Cup. With the purchase of some co-copyrighted content, we continue to deepen cooperation with game developers, fully integrating tournament content with our platform's operational characteristics to provide differentiated tournament derived content and customized user services. Meanwhile, aligning with the tournament’s content, we will explore more commercialization channels to improve the ROI of tournament’s copyright. Moving on to our monetization strategy. Our total number of paying users in the fourth quarter was 5.6 million with a quarterly average ARPU of RMB293. We continued our paying user segmentation strategy from last quarters, which included canceling marketing activities for new paying users with low rates of returns, maintaining our core users' readiness to pay and promoting more consumption of mid-range payment users. We also made progress in generating revenue from non-virtual gifting. For Q4, we continued to refine and promote our platform-wide membership service system, strengthened the companionship and interaction between streamers and platform members and consistently iterated membership features. In the fourth quarter, we launched sound effects and privilege gifts for members, leading to a sustained, steady increase in members renew rates compared with the third quarter, demonstrating high user stickiness among our fans. Furthermore, we extended our game-specific membership service to multiple segments. Based on the characteristics of each game, we launched customized game membership services to meet users' needs for in-game item. Going forward, we will strengthen our cooperation with game developers that fit into users' gaming needs and explore more commercialization channels. In terms of our product R&D and function innovation, we continue to deepen cooperation with game developers. In compliance with laws and regulations and based on our partial game-based sharing partnership with game developers, we integrated gaming data, content and function with DouYu’s content and gameplay, making live streaming content close fit with these games. For example, the Honor of Kings live streaming channel, users can easily team up with streamers and other users to play the game through the join with one-click function, making user streamer interactions significantly simpler than before. In the past, users had to manually add friends into the game to form teams. In addition, with this excited more game-related data and gaming strategies through partial game data sharing in games such as [indiscernible] and Peacekeeper Elite, further optimizing our user experience and stimulating live streaming engagement. Overall, in a challenging year of 2022, we created a healthy and vital gaming content ecosystem through various operational strategies, including adjusting revenue-generating activities and increasing investments in self-produced content, thereby maintaining stability in the company's overall business and financial performance.
