Many people have formed an inherent concept that cream is only suitable for southerners. As a matter of fact, the ancient people took the cream prescription regardless of the north and south, and even the climate characteristics in the north were more suitable for taking the cream prescription for two reasons: First, it was cold in winter in the north, which was more suitable for winter tonic, and TCM health care paid attention to the unity of nature and man. According to the characteristics of spring, summer, autumn and winter storage, winter collection is the most suitable for tonic. The colder the weather, the better the effect of Su Jiang's collection, the more beneficial the cream, and the better nourishing effect for northerners. Secondly, the winter in the north is longer than that in the south, so the tonic time can be grasped more flexibly, and the time for taking the cream is relatively long.
