Tomb-Sweeping Day is one of the three major Halloween festivals in China. "Ghost Festival" is a festival to mourn the dead, as opposed to a festival to worship gods and land gods. The participants in Tomb-Sweeping Day are all the people, from princes and ministers to ordinary people, to pay homage to the dead souls of their ancestors on this festival. Since the Tang Dynasty, the imperial court has given officials a holiday and asked them to go to their hometown to visit their graves.
According to "Dream of Liang Lu" in the Song Dynasty, every time you go to Tomb-Sweeping Day, "officials go out to the tombs of the suburbs to show their respect for their thoughts." The number of grave sweepers is not limited to men and women, and they often go out with their families. In this way, grave-sweeping activities around Tomb-Sweeping Day often become the personal participation of the whole society. Within a few days, the country people came and went, and the scale was extremely prosperous.
