How to paste couplets with the character "福"
The word "福" on the door cannot be pasted upside down, it must be pasted upright. The word "福" on the door means "welcoming blessing" and "receiving blessing", which means "welcoming blessing". And the door is the entrance and exit of the home, a solemn and respectful place.
The word "Fu" can be pasted upside down on boxes, rice jars and other containers. The reason why the word "福" is pasted upside down is because many people use the homophonic pronunciation of "福来", which means that blessings (and also wealth) will always come to their homes, rooms and cabinets.
There is a special situation where you can paste the word "Fu" upside down. That is, if there is an accident at home during the year, friends who hope for good fortune can post the word "Fu" upside down.
