Of course, China on the Tip of the Tongue, which was broadcast by CCTV, gained a large number of fans even in such a bad time in the early morning. The main content of the program is the food ecology in all parts of China. Through many aspects of Chinese food, it shows the culture of ceremonies and ethics brought by food to China people's lives. See China's special ingredients and a series of elements related to food that constitute the unique temperament of China cuisine; Understand the exquisiteness and long history of Chinese food culture.

The target audience of this documentary is not only created for' foodies' who like food, but also targeted at ordinary normal people. It is indicated that the goal of this documentary is to let audiences at home and abroad appreciate the beauty of Chinese food through food, and then perceive the cultural traditions and social changes in China. Chen Xiaoqing said, "We are not going to shoot famous chefs' dishes, but ordinary people's home cooking", and said that in addition to presenting all kinds of delicious food, China on the Tip of the Tongue will also show the life of ordinary China people, show the story between people and food, and see the society through delicious food. The important theme of the film is the "change" of China: to show the audience the traditional farming China, but also to tell the audience that many China traditions are changing, and some people appearing in the film are likely to be the last generation to inherit the craft; Therefore, the film's creative team has established a shooting standard for choosing ingredients for this film: "Shooting food bearing the spirit of China people". In one episode of the film "Taste of Time" directed by Zhang Minghuan, a grandmother in Tai 'ao, Hong Kong, insisted on making shrimp paste with her husband for decades after her wife died. Zhang Minghuan said, "For her, shrimp sauce is no longer a simple food, but the sustenance of her life and emotions."

Tongue 1 takes food as the entrance and human feelings as the exit. In Tongue 1, you can feel the love of every food producer for food, which leads to many stories. Tongue 2, on the other hand, went straight to the humanistic feelings and photographed many people with "stories", but I didn't feel that they were really good at cooking or their love for the food they made. (In Tip Tip 1, the producer of food may be chosen because this person is the most authentic and popular, or because he has a deep chance with this food, while Tip Tip 2 may only choose the producer of food because the producer is cooking this meal for his son who doesn't go home often, or for a pregnant woman.)

The tip of the tongue is definitely not for the chef, so it is a bit too thin to look at the tip of the tongue only from the perspective of food. I think the tip of the tongue is a feeling for hometown and a belief in culture. My belief is home, and it is the taste of home. . Because no matter where you go, no matter what kind of delicacies, no one will forget the taste of his hometown.
