Not very useful, unless you can be a civil servant or institution, official, scientist, expert, writer and other high-end industry elites, or at worst, a state-owned enterprise or a teacher, it is useless. Otherwise, you still have to learn technology after finishing college. It is enough to learn culture in junior high school, but it is rarely used in senior high school. University technology is not good enough to catch up with technical schools, and now society pays more attention to ability and skills.
