The first big snow mountain climbed by the Red Army is located in Baoxing County, Ya 'an City, Sichuan Province.

The first big snow mountain that the Red Army crossed in the Long March was Jin Jia Mountain in Baoxing County, Ya 'an City. On June 2nd, 1935, the 4th Regiment of the Central Red Army 1 Division came to the mountainous area of Jin Jia as an advance team of the whole army and began this tragic journey. Mount Jin Jia is also called "Jin Jia Mountain", and in Tibetan it is called "Jiaji", which means it is very high and steep. The terrain is steep, the mountains are continuous, and there is snow all year round; The air is thin and the weather is changeable. The local folk song says, "Jin Jia Mountain, Jin Jia Mountain, birds can't fly, but people are even more unattainable. If you want to cross the Jin Jia Mountains, unless the gods come to earth. " .
