The vertical tattoo of the Palace of Life between the eyebrows is commonly known as "Sword Cutting" and scientifically known as "Zhen Xuan Tattoo". As the name implies, Tang Yin, a man with Zhen Xuan tattoo, has a shallow fate with his son all his life, and his personality is too competitive to have children easily. If one of the husband and wife is natural and graceful, they can have children. .

People with vertical stripes in Tang Yin are too upright, and they will stick to everything they do. They won't stop until they reach their goal, and they don't know how to turn back. But such a character often has a successful fortune, so people who have a sword in the palace of life can often achieve something.
