Driven to Join the Liangshan Rebels tells how Lin Chong, Lu Zhishen and others were forced to become Liangshan rebels. Lin Chong was the coach of 800,000 imperial guards. Gao Qiu’s foster son had his eye on Lin Chong’s wife and tried several times to take her but failed. He then plotted against Lin Chong and tricked Lin Chong into the forbidden military conference room. For that reason, Lin Chong was tattooed on the face and banished to Cang Zhou and was almost killed by the escorts on the way. Fortunately, he was saved by Lu Zhishen. But Gao Qiu’s son wouldn’t stop. He sent men to kill Lin Chong, who were killed by Lin Chong instead. Lin Chong had no choice but to go to Liangshan with the help of Lord Chai.
