Jiayuguan Guancheng is located in Jiayuguan City, Gansu Province, is the first gate of the Great Wall of China, echoing the Shanhaiguan in Hebei Province in the east. In the golden autumn of 2015, I had the opportunity to join my wife, departing from Zhangye, Gansu, and took the train to Jiayuguan, and visited Jiayuguan Guancheng, the hanging wall Great Wall and the first pier of the Great Wall scenic spot.
