The century-old cheongsam shop "Neon Tailor Shop" is on the verge of bankruptcy due to the impact of modern fast fashion. The owner and cultural relic restorer Zhang Wei suddenly received an order in the style of the Republic of China - requesting custom-made cheongsams with buttons embroidered with "Two Swallows Returning to their Nest". After taking the order, she discovered that the customer was actually her former boss Lin Shen who had used AI to change his face to disguise himself. In order to protect the secret recipe of cheongsam passed down by the family for three generations, and to track down the live broadcast reward fraud group behind Lin Shen, Zhang Wei teamed up with Su Xiaoman, a live broadcast celebrity who was deceived by Lin Shen, and Chen Mo, a cultural relic restorer who knew the costumes of the Republic of China, to start a game with cultural relic dealers and internet celebrity brokerage companies. In the end, she used the "Pan Kou Code Book" left by her grandma to crack the loophole in the AI face-changing algorithm. Not only did she save the tailor shop, but she also made the traditional Pan Kou craft popular through live broadcasts and realized women's self-awakening.
