Is Shanhaiguan the starting point of the Great Wall?

It starts from Hushan in Liaoning in the east and ends at Jiayuguan in Gansu in the west.

1. Hushan, formerly known as Maer Mountain, is made up of two towering peaks side by side, shaped like two erect tiger ears, also known as Tiger Ear Mountain. In the Qing dynasty, it evolved into today's Tiger Mountain, protruding from the Yalu River, with a lonely and flat terrain and a wide field of vision, and the fields and houses on the other side of Korea were unobstructed. As a country, the position of the Great Wall of Hushan really has military significance. Dandong was invaded by foreign enemies.

The tiger bears the brunt and has always been regarded as a military fortress. Anyone who knows the military knows that occupying the commanding heights is equivalent to controlling the initiative in the battle. It is logical to build the Great Wall on Tiger Mountain. China's ancestors lived to defend their country, and their responsibilities, obligations and their own lives forced them not to choose Tiger Mountain as a barrier. When Wang Zhihao, governor of the Ming Dynasty, boarded Hushan Fortress Prison, he wrote the poem "Climb Ma 'er Mountain and look at North Korea from afar".

Jiayuguan is located in the middle of the narrowest valley 5 kilometers west of Jiayuguan City, Gansu Province. The walls on both sides of the city pass through the desert Gobi. It is connected to the Great Wall of Montenegro in the north and the first pier in the world in the south. It is the westernmost entrance of the Great Wall in Ming Dynasty. It was once called the throat of Hexi in history. Because of its dangerous terrain and magnificent architecture, it is known as the first male pass in the world, even the pass. Jiayuguan is the traffic fortress of the ancient "Silk Road" and is known as one of the three wonders of the Great Wall of China (starting from Shanhaiguan in the east, going to Beitai in Zhongyou Town in the west and going to Jiayuguan in the west).
