Wang Rong
Wang Rong was probably born in 877. At the time of his birth, his father Wang Jingchong was the military governor ("Jiedushi") of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei), which the Wang family had held in "de facto" independence since Wang Jingchong's great-grandfather Wang Tingcou. Wang Rong's mother was a Lady He; it is not known whether she was Wang Jingchong's wife or concubine, but she was described as being virtuous and strict in discipline in her rearing of Wang Rong.
