What marks the official start of the mid-winter season?

The heavy snow solar term marks the official start of the mid-winter season.

"Heavy snow" is the 2 1 solar term in the 24 solar terms of the lunar calendar, and it is also the third solar term in winter. This solar term means colder weather and greater possibility of snowfall. After that, the weather will be colder and the temperature will be lower and lower. The ancients named this solar term "heavy snow" because "snow" is a product of cold and represents cold and rainy weather. This solar term is characterized by a significant drop in temperature, rain or snow. The name "heavy snow" is a metaphor, which reflects the climate change during this solar term. The cold current is active, the temperature drops, and the precipitation increases, but it does not mean that it will definitely snow in this solar term.

Heavy snow: wait _ _ not blare; Second, wait for the tiger to pay; Third, wait for the plum to stand out. At this time, due to the cold weather, _ _ (Hao Han bird) no longer sings; Because this is the peak period in Yin Qi, the so-called peak turn, Yang Qi has sprouted, so the tiger began to courtship; "Liting" is a kind of bluegrass, and it also feels the spiritual germination of the sun and pulls out new buds.
