Why is grave sweeping popular in Tomb-Sweeping Day?

Grave-sweeping is actually a kind of tomb sacrifice. Ancient emperors once defined it as a national ritual system. In ancient times, "the grave is not grave" means only digging graves and not building graves, so this day is mainly related to thinking and cold food. Later, it was "going to the grave to sweep the grave", which supported the feeling of offering sacrifices to sweep the grave.

At that time, even if people were thousands of miles away, Qingming would go back to his hometown to sweep the grave. The internal basis of sweeping graves, combined with the traditional "Ghost Festival" in China, can be more clearly understood.

Judging from the solar terms, the first frost turned cold, so we should wear more clothes to keep out the cold. Do ancestors living on the other side of the earth have the same needs? So there was the custom of giving them some clothes and money to make them spend the winter smoothly. The emotional logic of death is based on the ancient and simple concept of soul and ancestor worship. The original origin of "Ghost Festival" is like this, and so is the original origin of Tomb-Sweeping Day.

Grave-sweeping is popular in Tomb-Sweeping Day, which is actually the content of Tomb-Sweeping Day Cold Food Festival the day before. Therefore, sweeping graves has become an important social custom in Tomb-Sweeping Day. Because cold food is associated with Qingming, it gradually spread to sweeping graves in Qingming. Until later, sweeping graves in Tomb-Sweeping Day became a popular custom, which lasted for several generations.
