What's the story of Zhongyuan Day?

The Mid-Yuan Festival, commonly known as Ghost Festival and July 30th, is called Sanri Festival in Buddhism.

On the fifteenth day of the first month, the Han people call it Shangyuan Festival to celebrate Yuanxiao, which has existed since ancient times. On July 15, the Han people called the Mid-Autumn Festival a festival to worship ancestors. On October 15th, the Han people called the Next Yuan Festival, a cold food in memory of the sages.

July 15 of the lunar calendar is the Mid-Autumn Festival, and part of it is July 14. It used to be a small autumn, and many crops were ripe. Usually, people want to worship their ancestors, offer new rice and other sacrifices, and report the situation in Qiu Cheng to their ancestors. Therefore, during the Mid-Autumn Festival, every family should offer sacrifices to their ancestors, and when offering sacrifices, they should all salute like utensils. On July 15, I went to visit the grave to worship my ancestors.

During the Eastern Han Dynasty, Taoism set up three sessions and five festivals, among which July 7th was Moral Wax Day, which was also the day when regular Taoists came to graduate school for exams. The date of ancestor worship in July was later set on this day, and Taoism set the birthday of Zhongyuan Guan and the corresponding date of sacrifice on July 15.

Legend has it that all ghosts are released in the underworld on this day, and people usually carry out activities of offering sacrifices to ghosts. Anyone who has a new funeral must go to a new grave, but usually sacrifices ghosts and ghosts locally. Therefore, the Mid-Autumn Festival is a ghost-worship-centered festival and one of the biggest folk festivals in China.
