Seven elder brothers is a corpse dog, crouching an arrow, swallowing thieves, nontoxic, removing filth and stinking lungs, which means joy, anger, sorrow, fear, love, evil and lust. When he dies, seven elder brothers will disappear. Since then, the "body and spirit" produced by the new body belongs to the "material world of Shi Yang".

Three souls refer to "the soul of heaven, the soul of earth (or knowing the soul) and the soul of man", which is called "the light of the fetus, the coolness of the god and the quietness of the god" in ancient times, and some people call it "the soul of the master (or soul), the soul of the awakened person, the living soul" or "the god of yuan, the god of yang and the god of yin". Three souls live in the spirit, so people die and three souls belong to the three realms.

Three souls and seven spirits is the soul view of China Taoism. Three souls and six souls are all wrong. There is a folk saying that "after death, seven souls disperse, three souls return to the tomb, one soul returns to God, and three souls go to the underworld for trial and even reincarnation."
