It probably means that if a person is kind at heart, it can be seen from his face that he is a kind person; if a person is evil at heart, it can also be seen from his face, for example, if his face is full of violence kind of.

Because our emotions are often accompanied by a certain degree of physiological arousal. For example, when a person feels stressed, his brows will be furrowed and his facial expression will be tangled, but when a person is in a happy mood, he will smile. A person with low self-esteem usually has a sense of shame, so he often lowers his eyebrows and his behavior reveals his inner cowardice. A confident and optimistic person is cheerful, radiant, high-spirited, and looks very sunny!

Scientific explanation

Taoists believe that thoughts are born and will inevitably affect the body, such as happiness, peace of mind, refreshment, and good health in times of trouble. Being enlightened and generous will help to harmonize qi and blood, harmonize qi and blood, keep the five internal organs at peace, function normally, and keep the body healthy, which in turn affects the state of mind. A virtuous circle, naturally full of brilliance, harmony, bright eyes, and high spirits, which makes people's eyes brighten.

On the contrary, if you are always scheming or depressed, you will naturally look at everything from a different perspective and will not be able to talk and smile like ordinary people. For example, Lin Daiyu will think about bad things when encountering something, and this will last for a long time. , qi is not comfortable, blood is not flowing smoothly, nutrition is not enough, the body and mind are not full, the five internal organs are out of tune, and the six gods have no master. With such a physical condition, the face is green, yellow, thin, dull, the expression is often clumsy, and the eyes are dull. Gods, half-dead, etc., make people depressed when they see them, or at least uncomfortable, and their popularity naturally decreases.

So, although the body, hair and skin are received from the parents, how the face makes people feel depends on their own hearts. As time goes by, these signs will appear, which is not a false theory of the physiognomist.

The human body is composed of bones, skin, hair, blood, etc. The bones are the support, and the heart maintains life. Just like natural animals and plants, human mood and thoughts dominate the human body and mind. It is the ruler of life and the center of the brain. Other organs of the body are controlled by it and influence each other. The inner psychological state will be expressed through the external organs, and it will affect and change the external form through the accumulation of time.
