When the messenger returns and reports, Yang Hu laughs, says that Lu Kang too knew he could drink, and has the jar opened and poured. When his lieutenant Chen Yuan says that he fears there may be some treachery in it and that the Commander should drink slowly, Yang Hu laughs, says that Lu Kang is not a man who would poison anyone and there is no need for suspicion, and in the end tips the jar and drinks. From then on they send men to ask after each other and are constantly in contact; later, when Lu Kang falls ill, Yang Hu sends medicine he has prepared, and Lu Kang too tells his generals, who suspect the medicine, not to suspect it, and takes it. This is the only passage in the Romance where Chen Yuan's name appears. Romance, Ch. 120 §16–18
