Lin Xiao, who was once a talented chef but has now become a courier who has come and gone, was accidentally bound to the "Chinese Food Renaissance System". The mission is actually to save those street snacks that are on the verge of being lost, and the reward is the ability to understand all dialects in the world and even ancient languages. When he reopened his family food stall while riding a tricycle, he shocked the old street with a bowl of spicy noodles that could understand the nostalgia of diners. What caught him even more off guard was that the director who was ordered to shoot a documentary about the death of food was his ex-girlfriend Su Tang, who broke up five years ago due to different ideas. Now, she holds up the camera and asks him why he settles for the ordinary, and he answers with a revitalized sense of tradition. Lin Xiao gradually discovered that his ability was not only to communicate with people, but also to "listen" to the secrets of ingredients. While rescuing flavors forgotten by time, his old relationship with Su Tang also heated up again amidst the smoke. However, the ultimate mission of the system quietly emerges: to conquer the taste buds of an international food critic and the heart of a centenarian who only speaks an endangered dialect with a snack in a lost ancient dialect.
