The first season of the documentary "Tongue on China" is divided into seven episodes, each of which first summarizes the theme of each episode, then gives examples of the various cuisines, and concludes with a theme that summarizes the entire episode. Ren Changzhen, the film's executive director, said that the subplots of the first season of Tip of the Tongue refer to a book written by Carlo Petri, the founder of the Slow Food Movement, and that each subplot is based on the concept of Western gastronomy; for example, Ren said, "The first one is about botany, and that's about botany. The first article mentions botany, which is about species, nature, and the land, and from this article I extended The Gift of Nature", and "The eleventh article is about art, industry, and human knowledge, which seeks to protect and preserve food at a high cost and treatment, and in fact, this one spawned Secrets of the Kitchen ".
