It's the vernal equinox, what kind of clothes to wear.

Thin woolen cloth+thin sweater+thick stockings

Small suit+white shirt+cropped trousers

Young people usually wear primers and coats.

If the temperature is 15 degrees, young people can wear thicker coats, while infants and the elderly should wear more and thicker coats because their resistance is relatively weak.

If it is about 25 degrees, you can wear a single item, neither too hot nor too cold.

The vernal equinox is the midpoint of 90 days in spring. One of the 24 solar terms, around March 20 of the Gregorian calendar every year, when the sun is located at 0 (vernal equinox) of the yellow meridian. On the vernal equinox, the sun shines directly at the equator of the earth, and the seasons in the northern and southern hemispheres are opposite. The northern hemisphere is the vernal equinox and the southern hemisphere is the autumnal equinox. The vernal equinox is a new year in Iran, Turkey, Afghanistan, Uzbekistan and other countries, with a history of 3,000 years.
