The film "Wanding Bridge" is set against the backdrop of the Yunnan-Burma Anti-Japanese War of the Chinese Expeditionary Force during World War II. It is based on the memories of Shangguan Qing, a veteran of the Expeditionary Force, who returned to China to look for his relatives. It uses the fate and emotions of three young people, Shangguan Qing, Linghe, the company commander of the Expeditionary Force, and Yuxiang, a local Dai girl, in the war to reproduce the tragic and heroic history of the Yunnan-Burma Anti-Japanese War and recall the achievements of the Expeditionary Force in Burma. Wanding Bridge is a boundary bridge on the border river between China and Myanmar. It was first built in 1938 when the Yunnan-Burma Highway was being repaired. It was an important international transportation port for China's foreign relations at that time. In 1942, 100,000 Chinese Expeditionary Forces left the country from Wanding Bridge and went to Burma to fight against the Japanese army. During the years of fighting against Japan, they dealt a heavy blow to the Japanese invaders and created a glorious history of the Anti-Japanese War.
