when I was in junior high school in the 199s, I attended a middle school in Guangzhou. At that time, more than 9% of junior high school students wore three-point shorts and sandals that were short to the middle of their thighs in summer, and almost all junior high school boys in the same class wore three-point shorts in summer. This was the dress habit of middle school boys in Guangzhou more than ten years ago, and even most senior high school boys wore it this way. Super shorts are two-part shorts, right? In fact, it's very hot in summer in Guangzhou. The temperature is above 3 degrees Celsius from May to October, and it often rains. It's hard for northerners to imagine. It's true that I wore shorts and sandals in junior high school to suit Guangzhou's climate. After I changed to trousers and sandals in senior high school, I was so uncomfortable that I went crazy every summer. After a little exercise, my trousers were all sweaty. Although it was such a dress custom in the summer of 198s and 199s, I have never seen boys wearing shorts in primary and junior high schools.
