Lu Junyi, a character in the novel Water Margin, is Zhou Tong's apprentice, nicknamed "Jade Kirin". He is skilled in martial arts, travels westward with sticks and makes good use of spears. Originally a big family, the prodigal son Yan Qing was his servant. As the book says, "Lu was born in Beijing and grew up in a very wealthy family; No illegal father, no remarried relatives; Be careful when you do things with Jun, don't make trouble without reason, and don't take money. " His family is innocent, cautious and lives in Daming House. Song Jiang longed for his name. In order to strengthen the momentum of Liangshan, he wanted to coax it up the mountain. Strategists Wu Yong and Li Kui jy pretended to be fortune tellers and dumb boys, and went to Ruff to tell their fate. Hearing that he was born in the year of Jiazi, the ugly month, the day of Bingyin, and the time of Ding Mao, Wu Yong was shocked, saying that "within a hundred days, there will be bloodshed: the furniture will not be kept and will die by the sword", and advised him to go thousands of miles away from the southeast to avoid the disaster, and wrote on the wall "A boat among reeds, Jie Jun swims alone at dusk." The righteous man carries a three-foot sword, but he wants to cut off the traitors. " Hidden head is anti-poetic. Lu Junyi was arrested and wanted to go to Tai 'an to avoid disaster. When passing through Liangshan, he was ambushed and fought with Liangshan heroes. Lu Junyi was defeated, and when he fled by boat, he was captured alive by Zhang Shun, a white-striped man in Langli. Lu didn't want to become an outlaw, and Song Jiang didn't force him to put it back. When he returned home, his wife Jia had married the housekeeper Gu Li and framed him for colluding with the rebels. Lu Qu repented and went to death row. Thanks to Yan Qing, Shi Xiu and other heroes in Liangshan, they were rescued one after another. After I went to Liangshan, I got the second place.
