Write a greeting, where does the falling snow come from?

Xiaoxue is the twentieth of the twenty-four solar terms. On the 22nd or 23rd of the Gregorian calendar (165438+1October) every year, when the sun reaches 240, it is light snow.

The ancient book "Qunfangpu" said: "A light snow will snow when it is cold, but the ground is not cold and the snow is not heavy." The arrival of light snow often indicates the deepening of winter.

The weather is getting colder and colder, and the graceful snowflakes falling in succession add a touch of poetic romance to the lonely winter day.
