As today marks the 94th anniversary of the September 18 Incident — the start of China's war of resistance against Japanese aggression, it is worth remembering how teachers in Zhejiang province stood firm in the darkest hour, passing on knowledge and hope with their words, actions, courage, and sacrifice.

In Jiaxing, archival records preserve the legacy of Zhang Yintong (1898-1969), headmaster of Jiaxing No 1 High School and a lifelong patriot. After studying in Japan, Zhang returned to China with a firm belief in saving the nation through education. He became headmaster in 1931.

Jiaxing's proximity to the front line exposed schools to frequent air raids. While many institutions shut down, Zhang remained at his post. As the city prepared for occupation in November, he organized the full evacuation of staff and students, relocating the school to today's Bihu town in Lishui.

Between 1941 and 1942, with Japanese forces invading southern Zhejiang, Zhang led the school on another westward migration. The school became a beacon, attracting young people who braved enemy lines in search of an education. Many who studied in exile went on to become national pillars in the postwar era.
