1. Taotie, from the interpretation of "Cihai" we can see that there is no final conclusion on the original meaning of "taotie", but later generations gradually derived its meaning of gluttony and deliciousness. That’s all.

2. The great writer Su Dongpo once wrote in "Ode to the Taoist": "I gather the youthful beauty of things to nourish my old glutton." Among them, the word "Lao Tao" evolved from "Taotie". It can be seen that in the Song Dynasty, people had forgotten the original meaning of "taotie" and used it to refer to the hobby of food. The word "taotie" has gone through a process of transformation from a derogatory meaning to a positive meaning. It also refers to those diners who are particularly good at eating and have a good understanding of food culture and traditions.
