[1] Wang Ji'en was born in Shanzhou (Chinese: 陝州; pinyin: Shǎnzhōu, modern Shan County, Henan).
His original surname was Wang, but his adoptive father Gentleman Zhang named him Zhang Dejun.
He was one of the higher-ranked eunuch during the reign of Chai Rong,[1] the second emperor of the Later Zhou.
As he requested to change his surname back to his ancestral surname, Emperor Taizu of Song named him Wang Ji'en.
