Zhang Yanli, the manager of a five-star hotel, returns to her village to organize her younger brother's wedding banquet. Hoping to save 13,000 yuan, she decides not to hire a head chef or appoint a banquet supervisor, relying instead on pre-prepared dishes and the management procedures she learned in the city. She can calculate every expense down to the last penny, but she cannot calculate the human heart. Her uncle fights for the seat of honor, the groom's relatives find fault with everything, and the overwhelming number of guests leaves everyone scrambling for seats. To make matters worse, her fake broth, made from diluted cream and seasonings, is exposed in front of everyone, bringing the wedding banquet to the brink of disaster. Her father swallows his pride and personally seeks help, while Liu Dana, the former village banquet supervisor, comes out of retirement to save the day. Only then does Zhang Yanli truly understand: money can be calculated, but the human heart cannot. The city teaches you how to save money; the village teaches you how to repay kindness.
