killed during the battle. However, his reinforcement was one of keys for Wagang Fort to survive from Yang Lin's attacking. He was also the teacher of another great warrior, Zhang Shanxiang (张善相). Version 2 Ding Yanping was a friend of Luo Yi's, and he was also the teacher of Luo Cheng when Luo Cheng was very young. When Yang Lin was attacking Wagang Fort, he was invited to reinforce Yang Lin.
