Which of the 24 festivals is Tomb-Sweeping Day?

Tomb-Sweeping Day is the fifth of the 24 solar terms.

Qingming is a solar term representing phenology, which means sunny weather and lush vegetation. As the saying goes, "Qingming breaks snow, Grain Rain breaks frost." When the weather is clear, the climate in South China is warm and the spring is strong. However, before and after Tomb-Sweeping Day, cold air still invaded from time to time, even making the average daily temperature lower than 12℃ for more than three consecutive days, resulting in rotten seedlings of middle rice and dead seedlings of early rice. Therefore, it is necessary to avoid warm tail and cold head when sowing and transplanting rice. In the northwest plateau, livestock are weak under the influence of severe winter and insufficient forage, so it is necessary to guard against the harm of strong cooling weather after spring to old, weak and young livestock.
