Does it mean that there is no rain this rainy season?

I won't. Rain is the second of the 24 solar terms, which is located on the fifteenth day of the first month of each year (February 18-20). The sun reaches 330 degrees on the yellow meridian. At this time, the temperature rises, the snow melts and the precipitation increases, hence the name rain. Generally, the rainy and rainy solar term begins on February 18 or 19 of Gregorian calendar and ends on March 4 or 5. Rain, like Grain Rain, light snow and heavy snow, is a solar term reflecting precipitation phenomenon, and is not a sign of drought within a year.
