Dàoji in Chinese (1130 – 1209), born Li Xiuyuan, commonly known as Ji Gong (Tế Công), he was a Zen Buddhist monk, he possessed supernatural powers through practicing Zen Buddhism, which he used to help the poor and fight injustice. Unlike traditional Buddhist monks, Dàjì do not like to follow traditional rules. Dàojì is very kind and always ready to help ordinary people. He often heals people and fights against injustice.
Legend has it that, while cultivating Buddhism, Dàojì achieved supernatural powers. Many people who noticed his eccentric yet benevolent and compassionate nature began to think that he was the reincarnation of a bodhisattva, or the reincarnation of an arhat. He is widely recognized as the reincarnation of Arhat Hang Long, one of the Eighteen Arhats. Thereafter, he became known as Jìgōng ("Honored Helper"), a title of respect derived from the name of his monastery, Dàjì.
Before his death, Daoji became a legend in Chinese culture and a deity in Chinese folk religion. He is mentioned by Buddhists in folk tales and koans, and is sometimes called upon by prophets to assist in worldly affairs.
Later religions began to venerate Jìgōng as a deity. Not long after, Chinese Buddhist organizations began to recognize his compassionate efforts, which were incorporated into Chinese Buddhism. He is also introduced as an interlocutor in many classic koans of the Zen Buddhism.
