"Langya Pass" is an ancient saying, now called "Hukou", located in Youyu County, Shanxi Province today, specifically 30 kilometers northwest of the county. 1. Different names for "Langya Pass"
"Langya Pass" is one of the most important passes on the ancient Great Wall. This place was called "Shenhekou" in the Spring and Autumn Period, and this name was used in the Qin, Han and Sui Dynasties.
In the Tang Dynasty it was called "White Lang Pass", and in the Song Dynasty it was called "Langya Pass".
During the Ming Dynasty, this place was used to resist the southern invasion of northern peoples, and it was renamed "Shahukou" at that time. In the early Ming Dynasty, the Mongolian Tatars, Oasis and other tribes repeatedly invaded the Central Plains from the south using this as a breakthrough point. In order to resist the southern invasion of the Mongol Oasis, the Ming Dynasty sent troops from this mouth many times to fight, so it was named "Shahukou". At the same time, the Guankou Castle was built in the 33rd year of Jiajing (AD 1544), and a new castle was built outside the Shahukou Fort in the 40th year of Wanli (AD 1612), named "Pingji Fort". Zhongguan was formed between the two forts. The "Tongshun Bridge" in Zhongguan is the Separation Bridge and Ping'an Bridge at the west entrance. Every third day of the first lunar month, people hold sacrifices here to pray for the safety of their relatives in other places. Zhongguan is connected by walls from east to west, so that Shahukou is composed of three parts: Shahukou Fort, Zhongguan and Pingji Fort.
In order to ease the conflicts between the mainland and the northern grassland peoples in the Qing Dynasty, Emperor Kangxi personally changed the word "Kill the Hukou" to "Kill the Hukou". Since then, the name "Shahukou" has been used to this day.
This is a fortress guarded by military strategists. During the Warring States, Han, Northern Wei and other periods, there were generals who marched into the desert from here and fought on the battlefield. After the Qing Dynasty, it led to the outside of the mouth, the Hetao Plain, the Mongolian Plateau and even further places. "Shuoping Prefecture Chronicles" records: Killing the Tiger Passage "arches the sacred capital on the inside and controls the desert on the outside. It is the key point of the three Jin Dynasties and the key to the north gate." 2. Shahukou is the representative location of "Going to the West Exit"
There is a famous folk song called "Going to the West Exit". The so-called west exit refers to a famous population migration event in history. In the late Qing Dynasty, the Outer Mongolia region was vast and sparsely populated. In order to immigrate to the border, the Qing government gradually relaxed its policy and encouraged the reclamation of Mongolian land and the development of agriculture. In addition, due to the continuous wars in Shanxi and Shaanxi, natural disasters occurred frequently. Therefore, Countless people from Shanxi and Shaanxi left their hometowns and embarked on the arduous road north to the west entrance. According to records, the history of walking to the west entrance extends from the mid-Qing Dynasty to the Republic of China, a period of more than 200 years. This is one of the five most famous population migration events in modern Chinese history.
So, where does the West Exit refer to? The West Exit generally refers to the place engaged in agriculture and commodity trade in the Mongolian area north of the Great Wall. The approximate location is the current Hohhot and Baotou area, so it is different from From a perspective, Shahukou in Youyu, Shanxi, Fugukou in northern Shaanxi, and Dushikou in northern Hebei are actually within the scope of the west entrance. Nowadays, people generally regard the Tiger Killing Pass as the representative of "walking to the west exit". 3. The movie "Langya Pass"
There is a movie called "Langya Pass". This film is about what happened during the reign of Tang Tianbao. The film is named after the place at that time.
However, it can be seen from relevant records: In the Tang Dynasty, this place was not called "Langya Pass", but "White Wolf Pass". By the Song Dynasty, it was called "White Wolf Pass". This is called "Langya Pass". Therefore, to be precise, the name of the movie seems to be "White Wolf Pass". I don't know why the director named it "Langya Pass"!
