The origin of winter vacation can be traced back to the ancient farming society in China. At that time, farmers will have a leisure time in winter, because winter is the leisure period of agricultural production. During this time, farmers can relax and reunite with their families. This tradition of winter vacation has also been passed down and adopted by schools and education systems.

2. After Prussia invented K 12 education system and compulsory education system, schools began to arrange educational contents according to age and academic progress. In the meantime, the school will have a summer vacation so that older children can go home and help with farm work. This is summer vacation.

The winter vacation is at the end of the Gregorian calendar, because there will be many religious festivals at that time, such as Christmas and Easter, and the school will have a holiday, because of the high operating cost and the high probability of accidents.

The existence of winter vacation is also to let students get enough rest and relaxation. Students will face great pressure and burden during their study in school, and winter vacation provides students with an opportunity to temporarily put aside their studies, relax, reunite with their families and engage in some recreational activities or travel.

The origin of winter vacation is closely related to the tradition of farming society, the evolution of education system, students' academic pressure and physical and mental development. Nowadays, winter vacation has become a long-awaited period of time for students. Let's enjoy this wonderful holiday!
