In the early years of the Republic of China, the New Culture Movement and the May Fourth Movement surged, disturbing the tranquility of Chongli School in Jiangnan. Shen Yue, a supporter of new ideas who came from a small family in the city, uses vernacular writing as a blade to break the shackles of old ethics on women, and is eager to use knowledge to enlighten people's wisdom; Gu Shuhuan, a guardian of the old culture nourished by a scholarly family, uses classical Chinese as a shield, adheres to the ethics passed down for thousands of years, and firmly believes that tradition is the foundation of civilization. They present a love that blends the old and the new, a hymn that resonates with family and country. Let's see how the two souls are tempered in the wave of change to become the light that illuminates the times.
