I was lucky enough to live with the principals for two days. In those two days, I ate, drank and slept with them and studied with them (because there was no other way, I had to accompany them). Their work and rest habits are the most important reason why I can't persist. Get up early in the morning and go to bed late at night, just like a machine that keeps running.
Their routine is about getting up at six o'clock in the morning, then washing up, and going to the playground to recite professional knowledge such as words at half past six. After seven o'clock, they will have breakfast, and after breakfast, they will go to the library to study for themselves. During this time, they will become quite quiet, sleepy and bored, so they just sit there quietly and study as if the whole world had been forgotten by him, which is really beyond the reach of ordinary people!
At noon, they will have a small lunch break. After lunch break, they will get up and go to the library to read. Then, again, they will sit all afternoon. Go to eat again. Go back to the dormitory at night, or study, and rest until midnight. Sometimes I think these schoolmasters must have strong willpower! Why else would they be so regular?
They usually take part in various activities in the class, as well as the sports meeting held by the school. As long as they participate, they will get a good ranking. They also go out to eat occasionally, in order to release the pressure of studying for so many days. But unlike us, they don't always stay in the dormitory to sleep or play with their mobile phones. They will take time out to do what they want. For example, on weekends, they go outside to tutor students, and we are sleeping. I think the gap is widening bit by bit, so I must study with them and become a university tyrant together!
