Are there any interesting places in Zhangjiakou?

In my opinion, the scenic spots in Zhangjiakou are very rich and varied, mainly based on the history of geography. From today's point of view, in some dynasties, Zhangjiakou was regarded as a border town, the northern part of Inner Mongolia prairie was southern Xinjiang, and the Central Plains dynasty was the city. So it has created a variety of scenic spots in Zhangjiakou ~

Great wall:

Zhangjiakou has always had the Great Wall Museum. In order to resist the invasion of nomadic people, all previous dynasties paid attention to building the Great Wall here. Zhangjiakou has 1800 km of the Great Wall, which was built in the Warring States, Qin and Han Dynasties, Southern and Northern Dynasties, Tang and Ming Dynasties. Although the Great Wall in Zhangjiakou is long, most of it is scattered in the wilderness and cannot be visited. The Great Wall, which has been opened as a scenic spot, is the Dajingmen section, which was built in the Ming Chenghua period and is one of the four passes of the Great Wall. According to the current understanding, this used to be the national gate. Dajingmen is located in the north of the city, and many buses can reach it. It's convenient to visit. ?

Ancient city:

Where there is the Great Wall, there are cities guarding the border. At that time, a series of ancient cities were built along the Great Wall, immigrated from the Central Plains and settled in the frontier. However, with the passage of time, the border line of that year became inland, and the city guarding the border lost its original function. The largest castle group in Zhangjiakou is located in Yuxian County, Zhangjiakou, which was built in the Ming Dynasty. These castles were built to resist the cavalry of nomadic people in the north. People in the castle usually farm and serve as soldiers in wartime. After hundreds of years of social development, a castle and a village have been formed. Therefore, to tell whether a village has a history in the local area, it is only necessary to see whether there are walls and gates. Locals call a village without inside information "Nomura". Yuxianbao recommends Shangsu Town, Wenquan Town and Beiguan Fort. There are various temples and old houses in the castle, which are khaki on the loess plateau as a whole.

Grassland:

North of Zhangjiakou is the southern edge of Inner Mongolia prairie. Zhangbei and Guyuan under Zhangjiakou are grasslands, and the most famous is Grassland Tianlu, which is a country road from Yehuling in the west to Huapiling in the east. The undulating roads are built along the terrain, with grassland scenery on both sides. Guyuan is farther north than the grassland road in Zhangbei, and it is closer to the grassland landscape. The lightning river also flows through here, adding a bit of agility to the grassland. Guyuan has lightning river reservoir, Swan Lake, dressing building and other attractions. Zhangbei to Guyuan is very suitable for walking around the city for two days on weekends.
