Meng Zhixiang
Meng Renzan was born in 919, in Taiyuan. His father Meng Zhixiang was then an officer under Li Cunxu the Prince of Jin, and had married Li Cunxu's cousin as his wife. Meng Renzan, however, was not born of her, but rather of a different Lady Li — one who had previously been a concubine of Li Cunxu's, but whom Li Cunxu had awarded to Meng Zhixiang as a concubine. He was Meng Zhixiang's fifth son but the third to grow up.
