Later, on this day, people did the same, offering sacrifices to ancestors and sweeping graves. This custom has been handed down from generation to generation and has become a fixed custom of the Chinese nation. At first, Cold Food Festival and Tomb-Sweeping Day were two different festivals. When the Tang Dynasty came, the grave-sweeping day was designated as the Cold Food Festival.

Tomb-Sweeping Day gas lasts 15 days. As a solar term, Qingming comes after the vernal equinox. At this time, the winter has passed, the spring is full of vitality, the weather is fine, the fields are bright and clean, and the vitality of nature is everywhere.
