"The Story of Yue Fei" says the Water Margin bandit Lin Chong was his student. In the Water Margin's 9th chapter entitled “Chai Jin Keeps Open House For All Bold Men, Lin Chong Defeats Instructor Hong in a Bout with Staves”, it reads, “Chai Jin said to the man, whom he called Arms instructor Hong: ‘This is Arms instructor Lin who teaches the art of spears and staves in the Eastern Capital's Imperial Guards.’”
