This time, it was the case that Chao Gai and others defected to Liangshan. "How to leave no one here, let alone leave no one here" is the antonym of "Leave no one here, leave no one here", which means that Classical and others intend to stay in Liangshan, while "The one who should stay is afraid of staying" means that Wang Lun, as the owner of the water margin, should take the initiative to invite Classical and others to stay, but he is afraid that they will stay. My personal understanding of "staying in misery" is that Lin Chong was unlucky and drifted from place to place for half his life, not that it is difficult for a master to stay (Chao Gai and others). "Hospitality" is naturally Lin Chong's invitation to classical people to stay.
