The king in this allusion is Cai Huangong. It tells the story of Bian Que, an imperial doctor, who visited Cai Huangong many times, repeatedly pointed out Cai Huangong's illness and suggested that he should be treated urgently. In the story, Cai Huangong didn't listen to advice, which led to a serious illness, until he was finally cured and died. The story shaped the images of Bian Que and Cai Huangong, and with Cai Huangong's tragic ending, it warned people to be wary of muddling along and be good at listening to others' correct opinions, otherwise the consequences would be unimaginable. Besides, of course, there will be other interpretations. It is because of these interpretations that the world attached the word "taboo for illness and medical treatment" to Cai Huangong. For example, the People's Education Edition of Chinese. The second volume for fourth-grade teachers said: "Make students realize the truth of preventing slight delay, listening to the correct opinions of others, not being afraid of getting sick and seeking medical treatment, and not sticking to their own opinions." For another example, the conclusion of China Student Encyclopedia is: "Han Feizi wants to illustrate that everything has subtle changes and good or bad omen through the story of Cai Huangong's fear of going to the hospital." "Bian Que meets Cai Huangong" vividly depicts the images of Cai Huangong who is afraid of disease and medical treatment and Bian Que who is good at medical treatment.
