1, all year round. Spring Festival couplets are auspicious, so it is necessary to remove the "old" Spring Festival couplets and paste new ones in the coming year, which means to bid farewell to the old and welcome the new, and have a good year. In this whole year, if the Spring Festival couplets are damaged, they need to be repaired in time.
2, the festival said. As one of the magic weapons to drive away the Year of the Animal, Spring Festival couplets can be picked after the Year of the Animal.
3. Natural shedding theory. The so-called natural falling off means that after the Spring Festival couplets are posted, no one cares, and the Spring Festival couplets are hit by wind and rain and naturally fall off. Or, when you see the Spring Festival couplets ruined by the wind and rain, just take them off.
Hanging Spring Festival couplets is very particular about:
Spring Festival couplets are not torn off casually after the Spring Festival. The more firmly they are pasted, the more they can be preserved for one year. When the Spring Festival couplets are posted before the Spring Festival next year, they will be posted on the old ones. The correct format should be, when face to face, the upper part is on the right and the lower part is on the left, because when Chinese characters are written vertically, they should be read from right to left.
But the horizontal criticism of Spring Festival couplets is written from left to right, which is also caused by contemporary reading rules.
