Why can't beginning of spring sleep after five o'clock in the afternoon?

Generally speaking, there are beginning of spring in many places, so I can't sleep at five o'clock in the afternoon. The main reasons for this statement are as follows.

First of all, this day in beginning of spring heralds the beginning of the spring year in Chu Xiao. It is not suitable for sleeping, because it is necessary to maintain vitality and mental state that day.

Secondly, 5 pm in beginning of spring is the spring break season in beginning of spring. At that time, you could grasp the new atmosphere of the whole year without sleeping, which was handed down by the ancients.

Third, this statement is actually a long-standing old saying. Now, no matter how many talents there are, they can sleep whenever they want, which has nothing to do with whether beginning of spring can set up any solar terms. Of course, out of respect for folk culture, we can do this.

In a word, China culture is profound. But we should also seek truth from facts. Come if you like. Happiness is the most important thing, right?
