Tomb-Sweeping Day is one of the 24 solar terms in the lunar calendar. At the turn of mid-spring and late spring, that is, 108 days from winter to the future, solar terms are set according to the year when the sun returns.

"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".
