Why can't plates be stacked together when eating a banquet?

There are several reasons why you can't fold the plates together at a banquet:

1. When eating a wedding banquet and cleaning up dishes, avoid overlapping empty dishes, so as not to commit the big taboo of "bigamy".

It is also taboo if the guests accidentally break the plate at the banquet. If you know how to crack it, you will pick it up and put it in the center of the stone mortar, indicating that it is broken and round, so that you can avoid evil spirits and seek good luck.

In a word, there are many rules for eating banquets, and many manners deserve our attention and observance.
