Zhuge Liang once went to the thatched cottage and asked which master came out of the mountain.

Liu Ba, a native of Hengyang, Hunan Province, was born in an official family and became famous at a young age.

The story invited by Liu Basan: Zhuge Liang urged to pay taxes in Hengyang. He had long heard that Liu Ba only knew more about the situation, so he came to Hengyang to look for it and found his home, but Liu Ba had gone out. On the second visit, the neighbor said he was fishing by the river. Looking for the river and seeing three or four people fishing, Zhuge Liang had to ask them one by one. The first person asked was Liu Ba, but he replied: I am a friend of Liu Ba. He has caught enough fish today and has come back. Zhuge Liang is still unwilling to give up. The third time I went to Liuba, I saw a fortune teller measuring divination, and I only heard that man accuse Sun and Liu of rebellion. Zhuge Liang immediately retorted, "Cao Cao's name is Han Xiang, but he is a real Chinese thief. After Liu Yuzhou was the great-grandson of Emperor Jing, the teacher of the uprising rebelled and followed it. What is disobedience? " The man left in a hurry without arguing. After three unsuccessful visits, Zhuge Liang wrote to persuade him. Liu Ba wrote back and said, "Everyone here is willing to join Liu Han. Now I have no choice but to fly away." Then he turned into Yizhou.

However, in 2 14 AD, after Liu Bei pacified Yizhou, Liu Ba finally joined the Party, which solved Liu Bei's financial difficulties after entering Shu, and co-produced Shu Han Fa Shu with Zhuge Liang.
