Hello, I didn't say you weren't welcome. Every subject in the college entrance examination has a choice, and the college entrance examination should still be like this, but it is more personalized than before. Students can avoid it when choosing and look at their weak subjects. History is compulsory for liberal arts, and physics is compulsory for science. This is the material of humanities and natural sciences, otherwise they will study in liberal arts and sciences, and teachers of any subject will be popular.
