The traditional Chinese lunar calendar divides the year into 24 solar terms. Minor Snow, (Chinese: xiaoxue), the 20th solar term

The traditional Chinese lunar calendar divides the year into 24 solar terms. Minor Snow, (Chinese; xiaoxue), the 20th solar term of the year, refers to the time when it starts to snow, mostly in China’ s northern areas, and the temperature continues to drop.
    An ancient Chinese book about plants explains that " in Minor Snow, the weather is cold and it is going to snow, while the earth is not frozen enough and the snow is light. " The temperature in most areas in the north drops to zero degrees and below. Meanwhile, in the lower and middle reaches of the Yellow River, the  average time of the first snow falls during the Minor Snow solar term. The snow is light and frozen at night, but melts quickly during the day.
    In China, starting in Minor Snow, the wind blows from the northeast a lot. Because it’ s still not bitterly cold, many people do not wear hats or scarves yet. In fact, according to an old Chinese saying, "the head is the place where all passages of the body gather". It’ s sensible to keep one’ s head warm.
    During Minor Snow, indoor heating begins to work, which means the air indoors is dry and most people might find their nose and mouth feel a bit dry. According to practices in traditional Chinese medicine, this accumulation of "inner heat" in one’ s body can cause problems, including oral ulcers and breakouts. The solution is to drink more hot soup, such as cabbage and bean curd soup, spinach and bean curd soup, and mutton and radish soup.
