There are no ghosts on the Ghost Festival.
Ghosts and ghosts are all fictitious in myths and legends and do not exist in real society. The Ghost Festival, also known as the Bon Festival, evolved from ancestor worship in ancient times. It is a major ancestor worship festival like Qingming Festival, Double Ninth Festival and New Year's Eve, and is a traditional cultural festival in Chinese areas.
July is the harvest season. In ancient times, people relied on the blessings of gods and ancestors for the harvest, so they would hold sacrificial activities after the harvest to celebrate the harvest.
