Should the Spring Festival couplets be posted on it or upside down? Anything to say?

As the Spring Festival is approaching, every household should put the word "Fu" on the door, wall and lintel. It's a long-standing folk custom in China to stick blessings on the Spring Festival. But how should I paste the word "Fu"? In this regard, Zhang Changyu, a famous sinologist and Chongqing-born professor of Sichuan Normal University, said that in the past, the word "fu" could not be pasted backwards, because the Chinese characters in China were square characters, which affected the appearance. With the development of the times, people began to change and develop the method of pasting the word "Fu". Inverting the word "Fu" means "Fu Dao". However, some Chinese characters are accompanied by 12 zodiac patterns, and the tiger, rabbit and dragon on the patterns are upside down. Some people think that tigers, rabbits and dragons are upside down, which means unlucky.

Therefore, there is no uniform standard for how to paste the word "fu", only the public's own preferences can be seen.

Lan Yong, director and professor of the Institute of Historical Geography of Southwest University, said that there is a saying that the word "fu" should be posted backwards, but there are two places where the word "fu" is posted backwards. One place is on the water tank and trash can, because everything in these two places has to be poured out from it. In order to avoid the dumping of blessings at home, they skillfully used the homophonic word "Dao" to paste the word "Fu" upside down. Use "Blessing" to offset "Blessing". Another place is on the cupboard at home. A cupboard is a place to store things. The word "fu" is posted backwards, indicating that the blessing has been reported to the house, house and cabinet. Although there is such a saying, with the different times and regions, there is no consistent standard on how to paste the word "fu", mainly depending on how the local convention was established at that time.
