The first lunar month, the New Year's Day, the New Year's Day and the New Year's Day are the first of the 24 solar terms.

It means "beginning", and spring represents warmth and growth. When the sun arrives,

Beginning of spring is located at the longitude of 315, and it is celebrated on February 3-5 of the Gregorian calendar every year.

Beginning of spring, one of the 24 solar terms, stands for "start", beginning of spring is the beginning of spring, and beginning of spring is when the sun reaches 3 15 degrees on February 4th or 5th every year. "twenty-four solar term": "The first month festival, the establishment, and the beginning are also ... the same in autumn and winter in long summer." Ancient "Sili" 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. China has a vast territory, complex geographical conditions, wide differences in climate and different seasons. Therefore, although the "Sili" can reflect the climate characteristics of the four seasons in the middle and lower reaches of the Yellow River, the specific climate significance of the "Sili" is not significant and cannot be applied to all parts of the country. The date of soil thawing in the middle and lower reaches of the Yellow River began in beginning of spring. The first weather in beginning of spring should be "East Wind Thawing", which is basically the same, but as a sign of the beginning of spring, it is too early. In climatology of China, the beginning of spring is usually defined as the 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 the busy spring ploughing season began in most parts of the country.
