What are the customs for the 30th anniversary?

On New Year's Eve, there are fish on the dining table. Don't put the word "Fu" on the door upside down. Fireworks are set off and sacrifices are made on New Year's Eve. Married daughters can't spend the New Year at their parents' home.

As the saying goes, "avoid the tail in the twelfth month, avoid the head in the first month", and there are many customs and taboos on New Year's Eve. These customs and taboos are the traditions left by our ancestors. The purpose is to celebrate the New Year safely and pray for a smooth and prosperous new year.
