Cunjin is a century-old cheongsam brand. Its inheritor, Chu Ning, was forced by her friend of ten years, Pei Shu, to order 50 high-end custom pieces at 500 yuan each, while bragging in group chats and live streams, only to come to the shop to try them on and sign. At checkout, the other party refused to pay 2.5 million yuan and pressured her with people. Refusing to keep quiet, Chu Ning used contracts, videos, and recordings as evidence to ensure the payment arrived. Unreconciled, the other party first spread rumors to smear her, then colluded with overseas capital to steal core tailoring techniques, and even created an accident to tamper with things at an international fashion show. Chu Ning presented her credentials in public, clearing Cunjin of suspicion and bringing the intangible cultural heritage cheongsam onto the world stage.
