One of the 24 solar terms. The solar term that begins in spring. On February 4th or 5th every year, when the sun reaches 3 15 degrees, it is beginning of spring. "Twenty-four solar terms": "The first month festival, the beginning, the beginning ... long summer, autumn and winter are the same." The ancient "Li Si" refers to the beginning of spring, summer, autumn and winter, and its agricultural meaning is "planting in spring, growing in summer, harvesting in autumn and storing in winter", which summarizes the whole process of the relationship between agricultural production and climate in the middle and lower reaches of the Yellow River.
In China's climatology, beginning of spring is usually defined as a day when the daily average temperature is stable above 10℃ every five days, which is inconsistent with the meaning of beginning of spring in the middle and lower reaches of the Yellow River. In late February, only South China really entered the spring. But this division method is more practical. After beginning of spring, the temperature rose, and most parts of the country began a busy spring ploughing season.
