If you don't continue to study hard, you will only be eliminated. Many students in these majors study all day and all night because of academic problems, so they will be called madhouse in order to complete their studies.

"The four madhouses of Peking University are: Institute of Mathematics, Institute of Chemistry, Institute of Physics and Health Center. As the name implies, the students involved are mathematics, chemistry, physics and biology. The reason why these four departments are called "madhouse" is mainly because those who can be admitted are "vicious people", and they can't get in only by the results of the college entrance examination.

Students want to be the top four students in Peking University, but only the results of the college entrance examination are far from enough. Students need to get the opportunity to participate in Peking University training camp in their sophomore year, although the name of each enrollment is different.
