Only the thumb has a half moon mark, okay?

Only the half-moon marks on the thumb are a symbol of deficiency of qi and blood, and the blood circulation is not very good.

If girls do this, they will almost always have dysmenorrhea.

Supplementing nutrition and strengthening exercise will improve, but not everyone will improve significantly. Some people need to use traditional Chinese medicine to organize them. It is best to have 8 and a half moon marks. If there are ten, it indicates that the metabolism is very strong and there is a risk of hyperthyroidism in the later stage.
