In his middle age, bankrupt and with his wife and children separated, Chen Jianguo held a yellowed family recipe book and traveled to a fantasy world where food culture can be called a desert. Here, the elves gnaw on hard bread, and the orcs gnaw on bloody roasts. He decided to start from a street stall, using Mapo tofu to ignite the passion of the orcs, using boiled cabbage to conquer the arrogance of the elves, and using a pot of steaming hot pot to melt the barriers between all races. This is not the legend of Long Aotian of one person, but the heart-warming journey of a frustrated man who used food to rebuild his "family" and heal others as well as himself. When the opponents in the Kingdom Food Competition use dark cooking methods to unscrupulous means, Chen Jianguo stands with his "children" and prepares to use the purest home-cooked dish to tell the whole world: the most advanced delicacy is called "going home".
