People's depth and personality: Generally speaking, people who are deep and long are very smart, especially those who deal with feelings perfectly. They are introverted but good at attacking, full of energy, like helping others, and have very strong personal ability and are calm and sophisticated. However, people who are shallow-minded and do things too wide are impatient, superficial, scheming and not deep.
People's depth and bearing offspring: in physiognomy, people with depth and length are those who have strong fertility and can have more children. However, we should look at people's faces as well as their ears. If people are deep and long, but their ears are thin and light-transmitting, they can have children, but their intelligence is not outstanding. Ears represent intelligence, that is, their learning ability.
Man's depth and health: man's life span is compared to an oil lamp, and man's kidney qi is equivalent to lamp oil. Only when there is enough oil will the lamp burn for a long time. If people are deep and long, then the kidney is full, the natural resistance is strong, and health is easy to live longer. If people are shallow, their physique is not very strong and their disease resistance is poor.
