Chinese medicine experts in Zhongjingtang, the TCM Health Center of Shanghai TCM Association, believe that "yang deficiency is external cold". In other words, the human body is weak in yang, lacking in qi and blood, and the yang is not solid, so it can't warm muscles to resist the invasion of external cold pathogens, so people are particularly vulnerable to cold. Modern research shows that the so-called yang deficiency constitution is mainly related to iron deficiency, hypotension, emaciation and hypothyroidism.

You can use Zhongjingtang's acupoint manipulation to smooth qi. First, you can operate the abdomen and back by rubbing it for a little longer, and then lift the skin of the lower abdomen vertically for twisting and massaging the Zhongji point. The whole set of manipulations can tonify kidney qi and effectively improve the symptoms of deficiency and cold.
