The little Cui Hua here is actually Kawanohiko. Kawanohiko came to Wilson Lee dressed as a China girl and Ye Lingqing and released the news to a man named Lao Qi. At the same time, Ling Ye Qing also found through investigation that the former dumb chef was a fake dumb, and his real identity was a comrade who defected to the enemy. Ye Lingqing found a chance to have a drink with Kawanohiko at night, and both of them were in a good mood. When drinking with Kawanohiko, Ye Lingqing got Kawanohiko drunk, and then he sneaked into the kitchen, pretending to go to the kitchen to find a hangover soup. He played it by ear and stuffed the note into the hands of the dumb cook, which was not discovered by Kawano Hirohiko.
