The historical witness of the gradual prosperity of Zhangjiakou. The origin of Zhangjiakou's name is also closely related to here. Zhangjiakou Blockhouse (also known as Xiabao) belonged to Xuanfu Town (now Xuanhua District (County)) in the Ming Dynasty, which was a well-protected land. In the fourth year of Xuande (A.D. 1429), Zhang Wenshi, the commander, began to build a castle named Zhangjiabao. Zhangjiabao is three feet high and 13 paces square, with one gate in the southeast, which is called "Yongzhen Gate" in the east and "Chengen Gate" in the south. In the eighth year of Jiajing (AD 1529), Zhang Zhen, a garrison, opened a small gate on the wall of the North City, which was called "Small North Gate". Because the gate was as small as a mouth and was built by Zhang Zhen, it was called "Zhangjiakou". Mongols and Buryats called it "Kalgan".
Zhangjiakou was once named Zhang Yuan. Zhangjiakou was renamed as Zhang Yuan after the National Government defeated Beiyang Warlords in 1928, and it was restored to its original name after liberation.
Edit the historical evolution of this paragraph In the Spring and Autumn Period, the north was the residence of Xiongnu and Donghu, and the south belonged to Yan State and Dai State. During the Qin Dynasty, the southern part was changed to Daijun and Shanggu County. During the Han Dynasty, it belonged to Wuhuan, Xiongnu and Xianbei. In Sui Dynasty, Zhuojun was in the east and Yanmen was in the west. In the Tang Dynasty, most of them belonged to Guizhou and Xinzhou of Hebei Road, and less to yu zhou of Hedong Road. In the Northern Song Dynasty, it was Wuzhou, yu zhou, Fengsheng, Guihua, Confucianism and Gui. Both belonged to Liao in the Southern Song Dynasty. Yuan belongs to Xuande House, Shangdu Road, Zhongshu Province, and Xinghe Road is located in the northwest (governing Zhangbei today). Ming was the headquarters of the Twelve Guards of Yanqing, Baoan, Yunzhou, yu zhou and Wanquan. In the Qing Dynasty, it belonged to the three halls of Koubei (Duolun Nuoer Hall, Dushikou Hall and Zhangjiakou Hall) in the north and Xuanhua House (governing Xuanhua today) in the south. In the second year of the Republic of China (19 13), it belonged to Koubei Road, Chahar Special Zone, Zhili Province. In the 17th year of the Republic of China (1928), Chahar province was established, with Zhangjiakou as the capital. In the 28th year of the Republic of China (1939), Zhangjiakou Special City was established. 19521February, the organizational system of Chahar province was abolished, and after the merger of Chanan and Chabei, it was called Zhangjiakou area, which was placed under the jurisdiction of Hebei province, and Zhangjiakou city was administered by the special area. 1May, 958, Zhangjiakou City was transferred to Zhangjiakou Zone. 1959 in may, the Zhangjiakou area was abolished, and the counties under its jurisdiction were placed under Zhangjiakou city. 196 1 year in may, the Zhangjiakou area was restored, and Zhangjiakou city and its counties were subordinate to it. 19671February, Zhangjiakou area was renamed Zhangjiakou area, which governs Zhangjiakou city, and the county is unchanged. 1983 1 1 month, Zhangjiakou was changed to a municipality directly under the central government of Hebei province. 1 July, 9931day, the land and city of Zhangjiakou merged and became Zhangjiakou city. 1On May 9th, 995, with the approval of the State Council, Zhangjiakou officially opened to the outside world.
During the Ming and Qing Dynasties, Zhangjiakou prospered in commerce and trade. 155 1 year, a "horse market" was opened outside Dajingmen, and the official cloth kettle was used to buy Mongolian Tatar horses and skins. 1570, Tatar leader Anda surrendered and was sealed, and Zhangjiakou was turned into a "mutual market place" between Mongolia and China. 16 13, Laiyuan Fort was built on the side of Zhangjiakou Fort. Based on Zhangjiakou Fort and Laiyuan Fort, Zhangjiakou gradually developed into the center of Mongolian and Chinese ethnic trade exchanges. At that time, there were rows of paving, merchants gathered, and "thousands of accounts" came from far outside the fort, and national commercial trade was very prosperous. 1676, the Qing army defeated Gerdan, opened the commercial road to Mobei, and established Dajingmen as a place for trade between Mongolia and the headquarters. By 1906, there were 1037 stores. Businessmen from Beiping, Tianjin, Shanxi and other places are coming to Zhangjiakou for business. 1860, Russian businessmen began to appear in Zhangjiakou. 1884, merchants from Britain, the United States, France and other countries came to Zhangjiakou to buy fur and wool in succession, and Zhangjiakou gradually became a big commercial port on land, "instilled by department stores, the place where business travelers return", with an average annual import and export of silver as high as150 million. Zhangjiakou's fur is increasingly influential at home and abroad. "The fur in the world is imported into the sea, and the Sifang leather market is priced and then traded", which has become the "leather capital" famous at home and abroad. Because the goods are excellent and beautiful, they enjoy a high reputation, and "mouth lamb" and "mouth skin" are well-known in the international market.

The main meteorological disasters in 2007 were drought, freezing injury, lightning, rainstorm, wind and hail, especially drought and freezing injury caused heavy losses in agriculture, animal husbandry and fruit industry.
Basic climatic conditions.
Bashang area in Zhangjiakou city lies between North China Plain and Inner Mongolia Plateau. The abrupt uplift of the terrain makes the continental monsoon rise and accelerate here, and the wind is strong all the year round.

However, in 2007, it was mainly thunderstorm weather, and the spatial and temporal distribution of precipitation was very different, and the regional drought was extremely serious, which led to the reduction of agricultural production. From the analysis of annual precipitation in the whole city, only Chongli and Yuxian are more than 400 mm; The annual precipitation in Kangbao, Shangyi and Huai 'an is less than 300mm. From the distribution map of precipitation anomaly, only Yangyuan and Yuxian in the southwest of our city have positive anomaly percentage, while other counties have negative anomaly percentage.
