How many Buddhist clothes and bags should be burned?

It's good to burn odd numbers of Buddhist clothes and bags. Burning buns to worship ancestors is a traditional custom. There is a custom of burning buns in the Mid-Autumn Festival, and there is a certain stress. The number of people is singular, and the specific number is not specified, mainly depending on local customs and personal wishes. Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
