Lin Miaomiao: I don't understand why we have to learn something that I may never use in my life, such as mathematics. I am sure that except for the college entrance examination, I will never use this mathematical knowledge in my life, so why should we learn it?

Lin Dawei: Throughout the dynasties, the most difficult people who are like time bombs are young people of your age. The average age of the 108 Liangshan generals was 21 years old, and Xiang Yu was only 24 years old when he started his rebellion against Qin. In order to manage you, the countries have to come up with some tricks to circle you and make you learn some useless time, so that all your time is occupied and you have no time to think about other things.
