After the solar term in beginning of spring, although the temperature began to warm up, it was still relatively low. Sometimes a small stream of cold air comes one after another, resulting in low temperature and rainy weather for several days, and sometimes there may be low temperature weather in late spring, which is quite unfavorable to agricultural production.
According to previous years' experience, generally speaking, the southern region will stay cold for about a month after the solar term in beginning of spring, and it will warm up in spring. In the north, it is even later. In most areas, it won't get warmer until Grain Rain or long summer.
