Is it spring after beginning of spring?

The twenty-four solar terms, called solar terms, are essentially solar calendars, reflecting the changes in the intensity of cold and warm when the sun shines on the earth. If the year is divided into four equal parts on average, the day of "beginning of spring" is beginning of spring.

But the definition of spring in meteorology is that the average daily temperature reaches 10 degrees Celsius for five consecutive days, and the first day is spring. This meteorological standard is different from the calendar in temperature. Spring in North China usually waits until around April.
