Analysis:
The bride lights a cigarette for the guests on the wedding day, aiming to highlight the excitement of the festival and the kindness of the new family to the guests. This is a folk custom.
Then a little prosperity means that life will be rich in the future. In addition, there is an atmosphere that makes it look lively, but after I have experienced it, I think there is another meaning, which is to test the bride's temper.
It should be noted that this is similar to the game of making a bridal chamber. Enough is enough and don't go too far. After all, everyone is happy, if it is a happy atmosphere.
