The double bird pattern is two lines that are close to the Yintang. People with the double bird pattern are too strong-willed and prone to harm. If the two lines form a "eight figure" shape, it means "Eight-character pattern".
People with the eight-character pattern in Yintang are hard-working, and they are prone to official disasters at the age of 40, and their female life will hinder their husbands. The lines on the left are called Luohou, and the lines on the right are called Jidu. If the two lines are of the same length, the disaster will be small. If the two lines are of different lengths, it will cause harm to others. If the right side is longer than the left, it will punish you or you will be in jail easily, so we also call this pattern "punishment pattern". If there are legs at the end of "punishment pattern", it can turn bad luck into good luck.
