"One meal, one world" consists of four series: "Hometown on the Tip of the Tongue", "Fantasy While Eating", "Traveling and Eating the World" and "Ancient People Eat". In the series "Hometown on the Bite of the Tongue", cabbage, pumpkins, fallen chestnuts in autumn and meat at country banquets all allow us to see beautiful pictures of our hometown. However, after watching this series, we have already formed "Fantasy while Eating" integrates the details of food with the lives of men and women in the city. It is humorous and makes people think about the beauty of life while reading it; "Traveling and Eating the World" depicts the cheap and good Luoyang The delicacies and Chengdu snacks give people a sense of China on the tip of the tongue; and "Ancient People Eating" allows us to appreciate another style of ancient people eating. Every food article is a journey on the tip of the tongue and a nostalgia on the taste buds. If the documentary "A Bite of China" allows the audience to appreciate the breadth and depth of Chinese catering, then Zhou Huacheng's "One Meal, One World" allows us to find the shadow of our hometown in catering. This prose has a light, fresh, and warm feeling when reading it. It removes the impetuousness of modern people and adds a touch of nostalgia.
