Where is the eastern end of the Great Wall in Wan Li?

The easternmost point of Wan Li Great Wall starts from Hushan Great Wall, and Jiayuguan is the western end of Wan Li Great Wall.

In 1990s, the Great Wall of Hushan discovered by archaeologists in Dandong replaced the former Great Wall of Wan Li with the "Yalu River in the East", which also confirmed the relevant records in Ming History.

There are two mountains at the foot of Jiayuguan Mountain in the southwest corner of Jiayuguan City. When the Great Wall of Wan Li was built in the fifth year of Hongwu in Ming Dynasty (1372). At that time, the Ming Dynasty general Sheng Feng took a fancy to the dangerous terrain at the northern foot of Jiayu Mountain, chose it as the first pass in Hexi, and began to build a city and set up a pass. After more than 100 years of expansion, a relatively complete defense system has been formed. During the Hongzhi period of the Ming Dynasty, it was rebuilt to prevent Turpan from invading eastward. This pass is magnificent and is known as "the first male pass in the world".

Extended data:

Origin of the Great Wall: During the Spring and Autumn Period and the Warring States Period, the princes of Yan and Zhao tried to resist foreign invasion. After the beacon tower was completed, it was connected with the city wall, forming the earliest Great Wall. Since then, almost all kings have strengthened and built the Great Wall. It is also called "Wan Li Great Wall" because it is tens of thousands of Li Long.

According to records, Qin Shihuang used nearly one million laborers to build the Great Wall, accounting for one twentieth of the country's total population at that time. At that time, there was no machinery, all the labor was done by manpower, and the working environment was very difficult, with mountains and cliffs. The Great Wall was built in the Spring and Autumn Period and the Warring States Period with a history of more than 2,000 years. Today's Wan Li Great Wall refers to the Great Wall built in the Ming Dynasty. People who have been to the Great Wall at all times and all over the world are amazed at its majestic momentum, grand scale, arduous engineering and preventive significance. It combines the wisdom, will, perseverance and endurance of the ancients. Therefore, the Great Wall is a rare treasure and an extraordinary cultural relic. It symbolizes the great will and strength of the Chinese nation and is the pride of the Chinese nation and the whole world. In the Ming Dynasty, in addition to the "outer" Great Wall, the "inner" Great Wall and the "inner three passes" Great Wall were also built. The "interior wall" starts from Pianguan at the junction of Inner Mongolia and Shanxi in the west, enters Hebei at Yanmenguan and Xing Ping in the east, then goes to the northeast, passes through Yuanyuan, Fangshan and Changping counties, reaches Juyongguan, and then reaches Huairou No.4 Pass from north to east, and is connected with the "Outer" Great Wall, with Zijingguan as the center, generally showing a north-south trend. The "Neisanguan" Great Wall is parallel to the "Inner" Great Wall in many places. In some places, the two cities are only tens of miles apart. In addition, a large number of "heavy cities" have been built. There are as many as 24 "heavy cities" around Yanmenguan.

According to historical documents, more than 20 vassal states and feudal dynasties built the Great Wall. If you add up the Great Wall built in past dynasties, it is about 10 Wan Li. The length of the Great Wall in Qin, Han and Ming Dynasties exceeded 1 Wan Li. China, Xinjiang, Gansu, Ningxia, Shaanxi, Inner Mongolia, Shanxi, Hebei, Beijing, Tianjin, Liaoning, Jilin, Heilongjiang, Henan, Shandong, Hubei, Hunan and other provinces, municipalities and autonomous regions all have the remains of the ancient Great Wall and beacon towers.
