The traditional Tomb-Sweeping Day of the Han nationality in China began in the Zhou Dynasty and has a history of more than 2,500 years. "Almanac": "On the fifteenth day after the vernal equinox, the bucket refers to Ding, which is used for Qingming, when everything is clean and bright, and when it is covered, everything is clean and bright, hence the name."

As soon as Qingming comes, the temperature rises, which is a good time for spring ploughing and sowing, so there is a saying that "before and after Qingming, we plant melons and beans". Tomb-Sweeping Day is a festival to worship ancestors, and the traditional activity is to sweep graves.
