Colleagues, I received notification this morning from Taida that our senior scholar and friend, Professor Wang Deyi, passed away on Monday April 29 at age 91 after lengthy illness. The Song-Yuan-Ming fields, and especially those who knew him personally, will miss him greatly. In addition to his multivolume indices to biographical materials from these dynasties, his scholarly articles and books will continue to enhance the understanding of these periods. Our condolences to his widow and their sons. Here is an announcement by Taida: https://homepage.ntu.edu.tw/~history/_news/news_20240430.html Sadly, Hoyt (Tian Hao)
