The origin of the university squatting at home: the original intention is a group of words that comfort themselves and are homophonic for college entrance examination students. Later, because the country popularized universities, the influence of universities gradually increased, and they were gradually widely cited by those with academic qualifications and those without academic qualifications. The word "squatting at home" is more popular: social occupations that have not entered the university, and little-known majors (for example, an old farmer said that he was squatting in the university agricultural science, which was originally intended to be a joke). Now it has developed into the cradle of candidates, affecting the whole post-80s generation.
