Liu Bei’s first son was his adopted son Liu Feng. He was originally the son of the Kou family of Luohou and the nephew of the Liu family of Changsha County. When Liu Bei first arrived in Jingzhou, he adopted him as his adopted son because he had no sons. Later, because Liu Feng oppressed Meng Da and did not rescue Guan Yu, Liu Bei resented him and was sentenced to death by Liu Bei. Later, Liu Bei had Liu Chan, the second emperor of Shu. Liu Chan was born to Mrs. Gan when she was in Xinye. The Romance of the Three Kingdoms mentioned that Mrs. Gan became pregnant because she dreamed of swallowing Beidou, so Liu Chan was nicknamed "Adou", and Liu Bei left him Liu Chan's posthumous edict "Don't do evil even if it's a small thing, don't neglect doing good because it's small" has become a wise saying for a generation. Liu Bei also had two sons born to Liu Bei's concubines, one son Liu Yong, who was named King of Lu, and the other son Liu Li, who was named King of Liang. Some people also say that Liu Bei also had a son named Liu Ming, but he was separated due to the war. He was exiled to Hanzhong and was adopted by a family. Later, after Liu Bei captured Hanzhong, Liu Ming came to visit him, but Zhuge Liang suspected that Liu Ming was genuine and threatened Liu Chan's throne ( Liu Bei likes to make his eldest son the heir apparent) and remove him, but there is no historical basis for this.
