Located 25 kilometers north province, the Battle of Xinkou site — a cluster of 47 weathered caves carved out of cliffs in 1935 — bears silent witness to a 23-day clash in 1937 that became an important chapter in the War of Resistance Against Japanese Aggression (1931-45). Kuomintang and Communist Party of China soldiers fought here together, effectively blocking Japan's southward advance, causing the invading army to suffer heavy losses.

As the country marks the 80th anniversary of the victory, local authorities have been enhancing efforts to honor the site's history and highlight its educational value by shining a spotlight on its united front against invaders and their battlefield heroism.
