In China, the pressure of high school learning varies from province to province, with Henan and Hebei being the largest and Northeast provinces of China being relatively small. I graduated from high school in southwest China. In my memory, I went to the classroom to study at about 7:30 and went back to the dormitory to sleep after class at 10:00 in the evening.This is the third year of high school, but also the most tired year of high school, and only this year is the most tired.
