In a small town in the south of the Yangtze River, 22-year-old literature student Mei Xiaoxiao discovered the diary of her great-grandmother Mei Lanfang while cleaning out her grandmother's attic. Mei Lanfang was a famous writer in the 1920s whose unfinished novel was interrupted by a forbidden love. Inspired by this, Mei Xiaoxiao decided to continue writing this work to pass on the family legacy. However, she faced pressure from her parents to choose a stable career and doubts about her writing ability. With the help of history student Zhang Wei, Mei Xiaoxiao delved into her great-grandmother's life, uncovered family secrets, and discovered the tragic fate of her great-grandmother's lover Li Wei. Mei Xiaoxiao found herself in creation and gradually overcame her inner struggle. Finally, she completed the novel and was recognized by the publisher. Like plum blossoms blooming in winter, she showed resilience and beauty. When the plum blossoms were in full bloom in spring, she and Zhang Wei expressed their feelings to each other and opened a new chapter in their lives. "Winter Wax Flowers" is a touching story about love, family and dreams, integrating the profound heritage of Chinese culture.
