Don't swim in the river and so on. Of course, these are feudal sayings, and not many people carry them out now.

Apart from some taboos, the most important thing is to worship ancestors. In our countryside, ancestor worship is always a top priority. No matter where you are, as long as your parents die at home, you must go home to worship at festivals, bring what the deceased usually likes to eat, take paper money and mingbi, while burning, tell your thoughts, and sometimes say something auspicious and willing, praying that your ancestors can bless your home.
Of course, different sounds in ten miles, one place and one custom. Although it is July 15th, it is the Mid-Autumn Festival. But in some places it is July 30, that is, July 14.

People who go out to work will go home for the holidays many days in advance, so the Mid-Autumn Festival is also called the day of reunion.
