On which days of the year should I burn paper for my old friend?

Burning paper money for the sacrifice of old friends;

1. General situation: the anniversary of ancestors' death, Tomb-Sweeping Day, Dragon Boat Festival, Ghost Festival on July 15th of the lunar calendar, Mid-Autumn Festival, Double Ninth Festival, New Year's Eve and New Year's Day.

2, special circumstances: such as the joy of moving.

The first or fifteenth day of the first lunar month of each month is the day of offering sacrifices to God.

If you miss this old friend very much, you can light three incense sticks or one incense stick at any time and pray silently to this old friend without burning paper money.

Good luck.
