Emperor Wen of Han
Liu Che was the 11th son of Liu Qi, the oldest living son from Emperor Wen of Han. His mother Wang Zhi (王娡) was initially married to a commoner named Jin Wangsun (金王孫) and had a daughter from that marriage. However, her mother Zang Er (臧儿) (a granddaughter of one-time Prince of Yan, Zang Tu, under Emperor Gao) was told by a soothsayer that both Wang Zhi and her younger sister would one day become extremely honoured. She then got the idea to offer her daughters to the then crown prince Liu Qi, and forcibly divorced Wang Zhi from her then husband. After being offered to Liu Qi, Wang Zhi bore him three daughters – Princess Yangxin, Princess Nangong (南宫公主) and Princess Longlü.
