What is the origin of Mid-Autumn Festival?

Mid-Autumn Festival is the name of Taoism, which is called July and a half in folklore, and it is called Arahara Festival in Buddhism.

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. It is a traditional cultural festival to commemorate ancestors, and its cultural core is to respect ancestors and do filial piety.
