Dou's son is joking.

After Sun Jian's death, Sun Ce took refuge in Yuan Shu and recognized Yuan Shu as his adoptive father.

→ Sun Ce should be called Yuan Shu's father.

Sun Ce is Sun Quan, Sun Shangxiang's eldest brother. In ancient times, the eldest brother was the father, and the adoptive father recognized by the eldest brother was also the adoptive father of the younger brother and sister.

→ Sun Quan should be called Yuan Shu's father.

Liu Bei and Sun Shangxiang are married, and Yuan Shu is Liu Bei's father-in-law.

→ Liu Bei should be called Yuan Shu's father.

So Liu Bei and Sun Quan should be called Yuan Shu's father.

Then, Zhou Yu is Sun Ce's adoptive brother, and Yuan Shu is Sun Ce's adoptive father.

→ Zhou Yu should be called Yuan Shu's father.

Yuan Shu is Zhou Yu's father, and Zhou Yu is Xiao Qiao's husband.

Xiao Qiao should also be called Uncle Yuan's father.

Through this, we can find a conspiracy-the fundamental purpose of Cao Cao's wanting to marry Xiao Qiao is to recognize Yuan Shu as his father.

Zhang Fei, Liu Bei's righteous brother, married Xia's sister, the sister of Cao Cao's family group.

→ Cao Cao (Xia Houdun, Xia, Coss, Cao Hong, Cao Chun and others) should be called Yuan Shu's father.

Liu Zhang is Liu Bei's brother.

→ Liu Biao and Liu Zhang should be called Yuan Shu's father.

Liu Biao is Huang Yueying's uncle and Zhuge Liang is Huang Yueying's husband.

→ Zhuge Liang should be called Grandpa Yuan Shu.

After studying the history of the Three Kingdoms for many years, I found that Yuan Shu was the super BOSS behind that history and the father of everyone in the history of the Three Kingdoms.

To sum up, Yuan Shu is Liu Bei's father. Liu Bei became brothers with Guan Yu and Zhang Fei.

Guan Yu and Zhang Fei called Yuan Shu their father, while Cao, Coss, Cao Hong, Xia Houdun and Xia were uncles.

Because Liu Bei married Sun Shangxiang, Zhang Fei married Xia Houba's sister, and Guan Yu and Liu Zhang were sworn brothers, and their father was their biological father. It is Xia's son, and Xia is Cao Cao's cousin.

Liu Chan married Xia Houba's sister's daughter again, and Liu Chan wanted to call Cao Cao and his grandfathers.
