The Han-Taeyangin's lungs are his largest organ, so the upper jiao, the lung group (lungs, esophagus, tongue, ears, brain, and skin) is most developed. Second largest are the kidneys, so the lower jiao, the kidney group (kidneys, large intestine, sex organs, mouth, bladder and bones) is well developed.

Pancreas is relatively small, so the upper middle jiao, the pancreas group (pancreas, stomach, breast, eyes, spine, muscles) is not well developed. Liver is the smallest organ, so the lower middle jiao, the liver group (liver, small intestine, navel, nose, waist and hypodermic tissues) is the least developed. Because the lungs are largest, the shoulders are broadest, but because the pancreas is small, the breast is not as broad as the shoulders. Women's breasts are not so large.

Looked at from behind, the Han-Taeyangin's shoulders and neck are so imposing, that he is easily distinguished from other constitutions, but looked at from in front, his chest is not very broad, like a Soumin. That characterizes the body shape of the Han-Taeyangin. Also, because of the small pancreas, the Han-Taeyangin doesn't become overweight. This is natural, because he is the opposite of the Yol- Taeumin, who easily becomes corpulent due to his largest liver and large pancreas. Also the underdeveloped organs in the liver group, among them the waist and the hypodermic tissues, keep him from getting fat.

Kidneys are large organs, so the organs of the kidney group, that is, the large intestine, sex organs, mouth, bladder, and bones, are well developed. He has solid bones and relatively large sex organs and is very energetic. Lee Jema wrote in his book that the Taeyangin woman is not fertile. But that concerns only the Yol-Taeyangin with her small kidneys. The Han-Taeyangin does not have problem giving birth due to the large kidneys.

The main characteristics of the Han-Taeyangin are due to the smallest liver. Among others, the brain belongs to the lung group, and is very well developed. He has a clear head and is inventive, intuitive, and sees things clearly. He depends more on spur of the moment inspiration or spontaneous thought than on forethought and planning; he seeks ideals more than reality. He generally denies reality and persistently seeks truth, the future, and abstraction. If taken to extremes, he can easily become lost in fantasy or daydreams.

A Taeyangin has too much heroism and high self-respect, and regards himself as superior to others. This thought appears unconsciously and hinders his harmony with other people. He is criticized for not being willing to compromise, for being arbitrary and egocentric. He hates to be criticized or admonished; he wants to do as he pleases. He is impetuous and resistant. He often attacks others and has little tolerance. He tends to blame others for mistakes instead of looking for his own blame, so he can be easily ignored by others.

Among the Taeyangins are some who, in isolation from society, live life alone in failure. This is the healthiest of the constitutions. Because of the smallest liver, even a little alcohol puts a heavy load on the Taeyangin's liver, but because of the strong body, many like to drink. This is a similar situation to that of Soyangin, who because of the smallest kidneys is the least energetic, but many of them have a strong sex urge.

Because of the largest lungs, Taeyangin has great lung capacity and is good at long-distance running. Many outstanding marathon runners and opera singers are Taeyangins. Many of those who, although slender, have a great booming voice in contrast to their body structure, are Taeyangins.

Ears belong to the upper jiao, ruled by the lungs, so Taeyangin has a well developed sense of hearing and musical talent even from infancy and can achieve great success in the field of music.
A tendency toward anger can easily make the blood collect in the head. Therefore the face reddens, the head aches and the ears ring. Anger is the feeling to be most careful about, because it can ruin his health more than any other.

Taeyangin can easily become indignant toward injustices of the country, society, or environment. If he can't control his anger, there is no medicine that will heal him. Unexpectedly, Taeyangin is scrupulous and takes offense easily. He doesn't easily tolerate offense. Nevertheless, he has great ambition and can become outstanding as a soldier or politician.
