Math scholar's social media debut kicks up concerns about his health

Chinese mathematical genius Wei Dongyi, who recently launched personal social media accounts, is now drawing widespread attention and sparking online discussions about his health.

Wei, an assistant professor and researcher at the School of Mathematical Sciences at Peking University, made his debut on Douyin and Xiaohongshu, also known as Red-Note, by posting a short self-introductory video.

"Hello everyone, I am Wei Dongyi," he says in the video, standing in front of a blackboard. Within a week, his Douyin account garnered more than 24 million followers, while his RedNote account attracted over 570,000 followers.
