Wisdom in network language refers to the homophonic meaning of mental retardation, which is often used to satirize others' poor ability and is a derogatory term.
The extended information is wisdom, a Chinese adjective, which comes from Confucius' Family Words: Three Religions: "Be smart and wise, and keep its stupidity." Also known as "Ruizhi". The word "Rui" was also used as a tribute to kings and queens in ancient times.
Wise network language: It comes from abstract TV. Because Zhang Shunfei is annoying and his fans are basically grumpy brothers, many people call him "mentally retarded". Later, Zhang Shunfei banned the barrage from calling him "mentally retarded", so the barrage was replaced by the words "wise" and "shunfei". Some people call him "old wise" because he just got out of prison. Satire those who don't know how to pretend to know and love to do things.
