Why can't we post Spring Festival couplets before New Year's Eve?

Because there is a folk saying about the four solar terms, it is said that it is the last day before the four solar terms of beginning of spring, Changxia, beginning of autumn and beginning of winter every year, that is, to bid farewell to this solar term, so it is called the four solar terms.

For example, this year's Lunar New Year's Eve is in beginning of spring, and the 29th of the twelfth lunar month is the last day of winter, which is also commonly known as "absolute winter". In absolute winter, it is considered unlucky for the elderly to stick Spring Festival couplets.

In fact, during the Chinese New Year, all kinds of statements and stresses are in the direction of "good". We should pay attention to things and words, like steamed bread, but we can't say it's broken. Suppose the steamed stuffed bun is laughing. These are folk customs and traditions, and they are also expectations for a better life.

Sticking Spring Festival couplets is our traditional custom, which has a history of thousands of years. It is also an atmosphere to bid farewell to the old and welcome the new, and it is also an expectation for a better life. People also posted new Spring Festival couplets, and the Spring Festival is coming soon. So posting Spring Festival couplets is quite famous and exquisite. It should be posted on the 30th of the twelfth lunar month, or on the 29th of the New Year, or in advance. Except for some people who need to post couplets in advance on business trips or business trips between two places, under normal circumstances, there are few people who post couplets in advance.
