How do you say that ancient schools have holidays?

Since the official imperial academy was founded by Emperor Wu of the Han Dynasty, there has been a phenomenon of students taking vacations in imperial academy. It was not until the Sui and Tang Dynasties that the student holiday system of Guo Zi School (namely imperial academy, also known as imperial academy) was established. According to records, it is divided into three categories: the first category is regular holidays, ten days is ten days, and students have a day off. At that time, the primary school was located in Kyoto, and most of the students lived on campus, so students from other places generally didn't go home during this regular holiday. The first festival is in May every year, when summer begins. At that time, plants are flourishing and the wheat in the field is ripe, so it is called "field festival". The third kind of leave is called "clothes-helping leave", which goes without saying. Because of the cold weather, it is necessary to add clothes, which is equivalent to 10 months of the solar calendar.
