Cold weather, cold hands and feet.

The most typical performance of people with insufficient yang is that their hands and feet are cold, and they are very sensitive to cold, so they are very afraid of cold. In addition, when I want to do something at ordinary times, I always have no energy and strength.

Some people have weak stomachs. If the weather changes, it will be filled with cold air if you are not careful, and your stomach will be stimulated and uncomfortable. When it's time to eat, they don't feel hungry. When they see food they don't want to eat, even if they barely eat a little, they will feel full because of gastrointestinal discomfort. If they eat too much, it will also lead to indigestion, bloating and pain, which means that the yang in the spleen and stomach is insufficient.
