Mid-Autumn Festival is the name of Taoism, which is called July 30 and July 14 in folklore and ancestor worship festival in Buddhism. Festival customs mainly include offering sacrifices to ancestors, setting off river lanterns, offering sacrifices to the dead, burning paper ingots and offering sacrifices to the ground. Its birth can be traced back to ancestor worship and related festivals in ancient times. July is auspicious month and filial month, and July 30 is a festival for people to celebrate the harvest and repay the earth in early autumn. Some crops are ripe, so people should worship their ancestors according to the law and report Qiu Cheng to them with new rice and other sacrifices. This festival is a traditional cultural festival to remember the ancestors, and its cultural core is to respect the ancestors and do filial piety.

In the Book of Changes, "seven" is a changing number and a resurrected number. I ching: "repeat the same thing and come back in seven days, and the day will be fine." The seventh is yang number and days. After the sun between heaven and earth is extinguished, it can be resurrected after seven days. This is the way of heaven and earth, the principle of yin and yang circulation. People choose to worship their ancestors on July 14 (February 27), which is related to the number of resurrection. The Mid-Yuan Festival in Taoism and the Kasahara Festival in Buddhism are both on July 15.

"July 30th" was originally an ancient folk festival to worship ancestors, but it was called "Central Plains Festival" and originated from Taoism after the Eastern Han Dynasty. Buddhism calls July and a half the "Kasahara Festival". In a sense, the ancestor worship festival in July and a half belongs to folk customs, the Mid-Autumn Festival belongs to Taoism, and the Arahara Festival belongs to Buddhism.
