You Tan Zhi, a character in Jin Yong's martial arts novel Tian Long Ba Bu, is the owner of Juxian Village and his father is You Ji. He is one of the most tragic characters in Jin Yong's novels. His parents passed away. On the road of revenge, he fell in love with the cruel and vicious A Zi and was put on a steel-toed quilt. He became a disfigured slave and went astray. A Zi, who practiced Falun Gong Dafa, owed his life, because he survived by practicing Shenzu Jing (the original version is Yijin Jing). By chance, ice silkworm's poisonous palm became a peerless master through swimming practice, and his martial arts was almost equal to that of Xiao Feng and Xu Zhu. Later, under the pseudonym Zhuang Juxian, he became the leader of the Beggars' Sect. A Zi was blind, so he gave his eyes to A Zi for treatment. Finally, A Zi didn't want to owe him a favor, so he dug out Jutanzhi's eyes and threw them back to him, holding Xiao Feng's body and jumping off the cliff. Swift and frank follow suit, and eventually a life of tragedy due to ill feelings.
