Lin Wanfeng, a tailor apprentice in the alley of the French Concession, and Lu Juanzhi, a student at Yenching University, became attached to each other over a cheongsam. The hand-made buckles triggered a subtle relationship between the two.
- **Identity Mist**: Lu Juanzhi appears to be the son of a wealthy businessman, but is actually the liaison of the Southern Revolutionary Party. Wan Feng gradually discovered his secret identity during the process of making clothes, but chose to keep silent.
- **Blood Romance**: The hugging and dancing at the concession dance concealed the transmission of information. Wan Feng used her cheongsam as a cover when the patrol room raided, and the two confirmed their feelings on the edge of life and death.
- **Choices in troubled times**: On the eve of Lu Juanzhi's transfer, Wan Feng worked overnight to make a buckle cheongsam containing a secret message. The maple leaves were flying when we said goodbye at the train station, and we agreed to use the red maple as a code for reunion.
