What's the point of putting the word "Fu" on the window?

1. In the folk tradition, there are only two places where the word Fu is posted. One is a water tank and the other is a trash can. Because both of them pour things from the inside, in order to avoid dumping the blessings at home, they use the word fu upside down. Offset the blessing with the blessing.

2. Another place is the cabinet in the house, which indicates good luck and wealth. Stick the word "Fu" upside down, indicating that Fu Bao has been at home, in the house and in the cupboard.

3. The blessing on the gate must be posted. Take the meaning of "welcoming happiness" and "accepting happiness". The gate is the entrance to the home, a solemn place. The blessings posted must be dignified and generous, and they must be posted correctly!
