Does the ancient private school in China have a rest day every week?

There are rest days, but not every week. The ancient calendar was yellow, and there were no weeks on it. In ancient times, rest days, known as rest days, were usually the 15th and the end of the month. On this day, civil servants rest and schools are closed. In addition, teachers in private schools can decide which day to rest, and generally choose: the fifth, fifteenth and 25th. Why choose "five" is also an ancient habit. On this day, there are more markets and more people go to temples to burn incense.
