The Second Season of China on the Tip of the Tongue is the first food documentary filmed with high-definition equipment in China. This documentary is positioned as a "high-end food documentary", covering a wide range of food areas, including more than 31 provinces, autonomous regions and municipalities in China, and even Singaporean food.

when interviewed, Chen Xiaoqing said that his crew didn't reveal their identity as China's crew on the tip of the tongue when shooting, and that the directors should eat every dish in the film themselves? . The four criteria for the selection of food in "The Tip of the Tongue" are: "health", the stewed food is not healthy, so it can't appear in the program, and "truth" means that the food itself is delicious and inherited, and there is no need to name the food with poetry; "relatively daily", that is, most people can eat it; And to "solve the problem."

Every episode of China on the Tip of the Tongue is not based on food. Food is just the starting point, and China society is seen through food. The whole film was shot by the diversity director according to the established diversity theme and then looking for the character stories that fit the theme.

After each diversity theme is established, the diversity director has to go through three stages before shooting: the first stage is the "copywriting" stage, that is, the diversity director reads a lot of books, investigates and writes copywriting about the theme; The second stage is the "investigation" stage, which is to determine what food diversity needs to shoot. Chen Xiaoqing, the general director, thinks that the road is also a process of obtaining food information, so in order to find the food appearing on the tip of the tongue, it is stipulated that the director of diversity can't drive by himself during the "investigation", but must take the public transportation "investigation" to facilitate continuous communication with people.

At the same time, in order to shoot some food that is relatively daily and more people can eat, the price of the ingredients is limited. In the second season, Chen Xiaoqing instructed the director to shoot only food with a price of less than 51 yuan at that time. Finally, according to a single food, go to various places to shoot, and find suitable people in the shooting area to express this kind of food and carry the story of the people in this area.
