Since ancient times, the Lijiang River has been known as the "Li Gateway" for its location in the main rush, and its strategic position in the period of the Anti-Japanese War is particularly important. At that time, if you want to reach the large rear area of southwest China, the land road is only by road, and the air passage depends on air transportation, and the Lijiang River is the only key node at the intersection of the two. For Chongqing, which was the accompaniment at the time, the Lijiang River was not only a key area for frontline defense, but also an important hub connecting the battlefield of North China with the large rear. In World War II, Lijiang Airport played a pivotal role, becoming the second largest military airport of the Allied forces after Kunming Air Base. General Chen Nader, the captain of the U.S. Flying Tigers, used this as a base for commanding his troops to launch a series of heroic air operations. The last large-scale war on the front battlefield of China's War of Resistance Against Japan, the "Xiangxi Battle" (also known as the Snow Peak Mountain Battle), was launched around the strategic location of the Lijiang River. The main goal of the Japanese invasion of China was to seize the Lijiang Air Base, so the battle was also known as the "Lijiang Defense War". After fierce fighting, the Chinese army finally won the decisive battle. Two months later, on August 15, 1945, Japan announced its acceptance of unconditional surrender. On August 21-23, the same year, under the global attention, the historic talks on health were held in Lijiang, marking an important milestone in China's comprehensive victory in the War of Resistance Against Japan.
