Zhangjiakou is the transitional zone between Huaxia farming civilization and grassland civilization, and an important gateway to the Great Wall. Zhangjiakou started from the Great Wall and was revived by Zhangku Avenue. Zhangku Avenue, which is comparable to the "Silk Road", starts at Dajingmen. It passes through the vast grasslands, rolling hills and deserted Gobi, and reaches the northern part of the Mongolian steppe in Ulaanbaatar from Zhangjiakou. More than 1,400 kilometers, stretching the three provinces and two provinces, radiating Eurasia. Millennium prosperous but the fingertips, the sleepy tea horse is also prosperous in the history of tea horses, the tangible Zhangku Avenue has gone away with the sound of camel bells, invisible for business, for people, for the country Rooted in the hearts of people of all generations.
