Li Tieguai is one of the eight immortals of Daoism. They are legendary beings said to have lived at various times and attained immortality through their studies of nature's secrets. They correspond in some measure to the eighteen luohan of Buddhism. Li Tieguai is always represented as a beggar leaning on a staff and holding or wearing a gourd. For further discussion see C. A. S.
