Metaphysics tells us how to increase one's yang.

There are many of them. For example, a strong man is full of yang, and a weak man is weak in yang.

Judging from the pulse condition, a person with strong beating is full of yang.

There are still many people who think that men are full of yang and women are weak.

In fact, to put it bluntly, increasing yang means increasing your masculinity. You can exercise more, eat some medicated diet and keep fit.
