What season does Tomb-Sweeping Day belong to that day?

Tomb-Sweeping Day is Tomb-Sweeping Day, which belongs to spring.

Among the 24 solar terms, Qingming is the only solar term that is both a solar term and a festival (the winter solstice is also a festival in history, but now it is no longer celebrated in most places).

The name of Tomb-Sweeping Day is related to the weather and climate characteristics at this time. The Western Han Dynasty's "Huainanzi Astronomical Training" said: "On the fifteenth day after the vernal equinox, the bucket refers to B, and the Qingming wind is coming." "Qingming Wind" is a refreshing and clear wind. "When I was in 100 questions" said, "Everything grows at this time, clean and bright. So it is called Qingming. " Although Qingming, as a festival, was only formed in the Tang Dynasty, Tomb-Sweeping Day Qi, as a symbol of time sequence, has long been known by the ancients and clearly recorded in the Han Dynasty.

Twenty-four solar terms are the climatic laws summed up by astronomers and people in ancient China in their life and production practice, which appropriately reflect the changes of temperature, phenology and rainfall throughout the year, and have indispensable guiding significance for people to arrange farming and sericulture activities on time. By Qingming, the temperature is getting warmer and the rainfall is increasing, which is a good season for spring ploughing and spring planting. Therefore, Qingming is an important solar term in ancient agricultural production. The farmer's proverb says, "Before and after Qingming Festival, point melons to plant beans" and "Planting trees is nothing more than Qingming Festival", which is precisely the truth. In the Eastern Han Dynasty, Cui Mang's Moon Order for Four recorded: "Tomb-Sweeping Day ordered a silkworm concubine to stay in the silkworm room ..." It is said that it was at this time that he began to prepare for sericulture. "Tomb-Sweeping Day" is just a solar term, not a festival.
