Tomb-Sweeping Day, what animals come out?

The animal represented by Tomb-Sweeping Day is the dragon, because the dragon represents the "rain god" in China traditional culture, that is, the "dragon king is in charge of rainfall" which is common in mythology. Therefore, the dragon in the zodiac should represent Tomb-Sweeping Day.

Rains in Qingming Festival is not an artistic imagination, but a poet's accurate description of the climate characteristics in Jiangnan at this time. There is plenty of rain on cloudy and sunny days, which can meet the needs of the growth and development of various crops. Therefore, there is a saying that "after the rain clears, the year is good." However, things are always the opposite. Too much precipitation can also induce wet damage and harm crops, so we need to be vigilant.

In the north, this is a suitable sowing date for many spring sowing crops, such as spring wheat, corn and sorghum. At this time, the weather gets warmer quickly, the soil thaws, and the soil layer can reach 5 to 10 cm deep, which is a good time to plant wheat in Dingling.

Spring wheat is an early spring crop with strong cold tolerance, which can tolerate low temperature of -6 ~-8℃ at seedling stage. "Ice seeds harvest by fire" is its biological characteristic. As long as the soil temperature reaches 2 to 4℃ and the soil humidity reaches about 50%, spring wheat seeds can germinate.

The solar term folk proverb "Clear the beginning of wheat in February and clear the end of wheat in March" is a good indication. Experienced farmers all know that wheat planted before Qingming has strong roots, good growth, drought tolerance and high yield; Wheat planted after Tomb-Sweeping Day germinates first and then takes root, with weak root system, poor growth, drought tolerance and low yield. If it is Tomb-Sweeping Day in February of the lunar calendar, we should plant spring wheat before Tomb-Sweeping Day.
