Sweeping graves is a kind of "tomb sacrifice" and a kind of "respect for time thinking" for ancestors. Its customs have a long history. In some places, sweeping graves is called "sweeping mountains" or "worshipping mountains", while in some places in the south, out of respect for ancestors, it is called "hanging mountains or hanging paper" or "eliminating evil words and calling it beauty". For example, when Tomb-Sweeping Day visits the grave, it is called going to the grave in the north and "worshipping the mountain" in the south coast, avoiding the words "grave" and "tomb".
Grave-sweeping refers to offering sacrifices to ancestors in a cemetery to express filial piety and yearning for ancestors, which belongs to a cultural tradition of honoring ancestors and pursuing the future with caution. According to the custom, influenced by traditional cultural psychology, China people have a strong sense of family, pay special attention to their families and ancestors, and have a strong sense of ancestor worship and returning home. This is a special way to commemorate their ancestors.
