1, China's traditional festivals are all lunar calendar festivals, because ancient calendar disciplines are all based on the lunar calendar, so Ghost Festival is no exception.

2. Ghost Festival on July 15th is taboo. July 15th in the lunar calendar is Ghost Festival, but July 14th is the fiercest. On July 15th, the ghost gate will be closed at night, and July in the lunar calendar is a ghost month. In some places, paper can be burned from July 1st to 15th, but July 15th is a positive day. Children should not go out on the night of July 14th, and those who have something to go out should come back as early as possible. The real paper burning is on July 15th.
