What about the day before and after beginning of spring?

Customs vary from place to place. In some areas, it is said that beginning of spring can't go out of the city the day before and the day after, can't enter the house, can't get married, and so on, depending on local customs.

Beginning of spring couldn't go out of the city the day before, because in the old Gregorian calendar, people believed that the five elements said that according to the law of natural change, after beginning of spring, the earth would be rejuvenated, so there would be no water, so it was called winter extinction. So, of course, the first day of spring is the last day. If we can't hold festive activities on Absolute Day, it will bring many disadvantages.

It should be noted that the day before and the day after beginning of spring's taboo have no scientific basis. Believe what is taboo at home, and don't believe what is not taboo. Compared with beginning of spring, there are still many people who choose to travel the day before, and nothing bad has happened.
