Introduction to Aizhai Highway: Aizhai Winding Highway was built in 1936 during the rule of the Kuomintang government, when Japan invaded China. In order to facilitate the evacuation and transportation of military supplies, Chiang Kai-shek personally took over as commander-in-chief to build the Xiangchuan Highway. The Aizhai Winding Mountain Highway was a natural hazard on the Xiangchuan Highway. In order to keep pace with the construction of this winding mountain road, more than 2,000 migrant workers died and more than 200 people died. On the mountain, there is a bronze statue of "Pioneer" and a "Cemetery for Employees Dead on the Xiangchuan Highway".
