田令孜
Biographical information about Chen Tao seems scarce; not only that, but, A. R. Davis mentions an "element of confusion", in this regard: and, "if" this is the same Chen Tao mentioned in connection with Tian Lingzi in the year 888, then either this date or the date of his death is wrong. It is known that Chen Tao was learned in Buddhism and Taoism and that he pursued the study of astronomy and alchemy, and that he spent most of his life in retirement in what is now Nanchang, in the Chinese province of Jiangxi.
