What do rain and Qingming mean in the twenty-four solar terms?

Rain is the second of the 24 solar terms. When the sun reaches 330 degrees, it is 24 solar terms of rain. At this time, the temperature rises, the snow melts and the precipitation increases, hence the name rain. The rain solar term generally starts from February 18 or 19 and ends on March 4 or 5. Rain, like Grain Rain, light snow and heavy snow, is a solar term reflecting precipitation.

Qingming is one of the 24 solar terms in the summer calendar. After the vernal equinox, before Grain Rain. "Almanac": "On the fifteenth day after the vernal equinox, the bucket refers to the ding, which is used for Qingming. Everything is clean and bright, and it covers the time (the temperature rises, the fog in the south is less, the sand in the north disappears, and the air permeability is good), hence the name."

Astronomical time: the sun is located at the longitude of the yellow meridian 15 degrees, and crosses the intersection point on the 4th to 6th day.
