A pastry master uses a humidity rule to blackmail the restaurant, walking out at a critical moment during a banquet and demanding a twenty percent equity stake! Cousin Dazhuang cannot stand this pretentious hocus-pocus. Without precision instruments, relying on folk banquet craftsmanship, he saves a twenty-table VIP banquet with a single pot of noodles. The master leaves holding a grudge, using pre-frozen ready-made goods disguised as intangible cultural heritage and skimming the apprentices' wages. A rival in the culinary king arena acts maliciously in secret, sealing off the gas and swapping the rich broth. Dazhuang directly splits the prized precious cutting board to set up a firewood clay stove. The blind old grandmaster's grievances are vindicated, and the fraudsters are caught. Full Man Lou opens its doors to take on apprentices, and the hot food full of life's warmth ultimately triumphs over flashy pretenses.
