Many people's misunderstanding of this word actually comes from "Yunnan", thinking that this word only talks about Yunnan's values and regional culture. Actually, it is not. The "old school Yunnan style" wants to convey a universal value of human beings. Simply put, it is to express the true face of human nature, not something anti-human.
There are many film and television works that convey the original appearance of human nature, and most Oscar films are based on this logic. Generally speaking, the essence of "old Yunnan style" is universal value.
