Wei Yiyin

Wei Yiyin is a Chinese expert, likely in the field of nuclear weapons, radar, or missiles, as indicated by the context of the news articles. They are newsworthy because their profile, along with those of other prominent scientists like Wu Manqing and Zhao Xiangeng, has been removed from the website of the Chinese Academy of Engineering (CAE), China's highest academic body for engineering science and technology. The disappearance of these profiles is a recent development, and the exact reasons for their removal are currently unknown. This event is significant because it raises questions about the status and activities of these experts and potentially reflects internal changes or security concerns within China's scientific and technological establishment.
