You don't have to attend. It is best to have a hospital certificate and no military training, but you can sit in a cool place and the tour guide doesn't insist on it. Military training is particularly important when you grow up, which is linked to final exams and scholarships. That is to say, military training must be done, but generally not. As long as you come to the military training ground in camouflage uniforms, you are qualified. Please, military training is extremely hard and the internal requirements are quite strict. Anyway, college is different. I don't know which college you are from, but I'm from the School of Economics, and my management is quite strict. You should be mentally prepared, hehe ~
