Core Viewpoint - The article discusses the recent surge in popularity of Wei Dongyi, a mathematician, following the launch of his Douyin account, which gained over 20 million followers in a short period. This phenomenon reflects a collective societal emotion and the potential for knowledge dissemination through social media platforms [5][8][41]. Group 1: Reasons for Opening Douyin Account - Wei Dongyi's decision to open a Douyin account was driven by multiple rational factors, including the need to combat impersonation and protect his image from malicious content [9]. - The account aims to serve as a platform for knowledge dissemination, where Wei plans to share mathematical content and engage more with the public [10][12]. Group 2: Social and Emotional Factors - The rapid growth in followers can be attributed to a societal admiration for pure academic spirit, contrasting with the current era's trends [13]. - The account also reflects educational anxiety, as many parents associate Wei's presence with good fortune in exams, turning the comment section into a "wishing pool" for students [14][16]. Group 3: Background of Wei Dongyi - Wei Dongyi, born in 1991, has a remarkable academic background, having excelled in mathematics from a young age and currently serving as an assistant professor at Peking University [18][20]. - His research focuses on partial differential equations and geometric analysis, with significant contributions to the field, including solving long-standing conjectures [22]. Group 4: Health and Lifestyle Concerns - Recent videos have raised concerns about Wei's health, as he appears physically unwell, which has prompted discussions about his lifestyle choices and social isolation [30][33]. - There is a call from the public for Wei to engage more with ordinary people to improve his communication skills and break his self-imposed isolation [35]. Group 5: Future Considerations - The article emphasizes that while the Douyin account is a significant first step, the future content must balance professional depth with public accessibility to avoid commercialization and maintain academic integrity [40]. - The ultimate goal is for Wei's account to facilitate a dialogue between academia and the public, allowing for the beauty of mathematics to penetrate the noise of entertainment culture [41][42].
