Which ancient book are Cut into the City and Blind?

"Cut the pole into the city" comes from China's first joke collection Laughing Forest (written by Ren Wei Han Danchun during the Three Kingdoms period). "One leaf is blind" comes from a protracted war.

Cut the pole into the city, laughing at the Lu people who hold the long pole and his inflexibility; I even laughed at my old father who saw the pole go to town and laughed at his cleverness as a teacher. The latter is not only ridiculous, but also harmful. This story has been passed down to the present, which has evolved into "catching fools" in Xi's "Exploring the Record" in the Qing Dynasty. The blind hero is the Chu people. This idiom tells us not to blindly believe any theory, but to go through scientific verification and investigation, otherwise it will make a joke.

Idiom is a major feature of traditional culture in China, which has a fixed structure and a fixed sentence, indicating a certain meaning. It is applied to a sentence as a whole, with subject, object, attribute and other components. A large part of idioms are passed down from ancient times and represent a story or allusion.
