According to Frost & Sullivan, we operate one of the largest online professional physician platforms in China based on registered physician users and average monthly active users in 2021. As of December 31, 2022, our platform had approximately 2.9 million registered physician users, and our average monthly active users reached 2.7 million in 2022. Additionally, there is a high percentage of veteran physician users on our Mace medical platform. As of December 31, 2021, according to the latest data published by the National Health and Health Commission, the total number of registered physician users with the title of Deputy Chief Physician or above on our Mace Medical Platform accounted for 67.1% of the total number of physicians with the title of Deputy Chief Physician or above in China. We believe that a large number of veteran physician users are critical to our business. Since senior physician users have a relatively high demand for medical research, they are important customers of our physician platform solution and a key data source for RWS solutions. Furthermore, they are the most important targets for our accurate omnichannel marketing solutions, since their familiarity with certain drugs and medical devices will guide their prescription decisions, and we believe that their opinions are also critical for pharmaceutical and medical device companies to upgrade their medical products. We are able to provide physicians with high-quality academic medical content and drive the growth of the number of users on our Mace medical platform. Over a period of track record, our content production team built massive amounts of academic and medical content on our platform, achieving comprehensive coverage of almost all medical fields. As of December 31, 2022, the content of our Mace medical platform covers (including) about 644,000 research results and about 195,000 materials on the latest medical developments. We are also collaborating with a number of KOLs to develop academic medical content in the form of online education courses, mainly including explanations of the latest medical evidence and findings, developments in medical research, and industry guidelines. We believe that providing comprehensive academic medical content will help us create an endogenous physician platform that can independently attract physician users and cultivate user loyalty without relying on traffic from third party sources. The number of registered users increased from about 3.4 million as of December 31, 2020 to about 4 million as of December 31, 2021, and further increased to about 4.5 million as of December 31, 2022. The number of registered physician users increased from about 2.3 million as of December 31, 2020 to about 2.6 million as of December 31, 2021, and further increased to about 2.9 million as of December 31, 2022.
