Jian Yongzhi advised Liu Bei: There was a severe drought in central Shu in one year, and the grain harvest in the whole territory failed, in order to ensure that the people had grain to survive, Liu Bei ordered that all parts of central Shu should ban winemaking during the year, and the brewers should be punished with felonies. A minister asked: No wine is found, only winemaking tools, how can I do it? Liu Bei replied: There are winemaking tools that can make wine at any time, and those who have winemaking utensils are guilty of the same crime as winemaking.

As a result, the prisons were full, and the real winemakers did not catch a few, and most of the people who were caught were searched for winemaking tools, all shouting that they had been wronged, and the people also complained.

One day, the minister Jian Yong and Liu Bei traveled in a car to inspect the people's feelings. There was an old man and a young woman in front of me. Jian Yong suddenly shouted at Liu Bei: Ask the lord to order the two dog men and women to be taken down and punished, they want to commit adultery. Liu Bei Daqi, ask why? Jian Yong said that the man and woman carried the tools of adultery with them and tried to commit misconduct. Liu Bei laughed and said: I understand the meaning of sir. Therefore, the order was revoked.
