Wang Yanzheng
It is not known when Wang Yanzheng was born. His father was Min's first ruler, Wang Shenzhi (Prince Zhongyi), but his mother's identity is not recorded in history. Further, while his older brother Wang Yanxi (the third among his brothers to rule Min) was said to be Wang Shenzhi's 28th son, Wang Yanzheng's birth rank is also not recorded in history. (However, as Wang Yanzheng was not mentioned on the tombstone of Wang Shenzhi's wife Lady Ren Neiming, he was likely born after Lady Ren's death in 918.)
