40. Travel in China "Tianjin·Huangyaguan Great Wall"

In the vast land of northern China, there is an ancient defense line that stretches thousands of miles. It crosses high mountains and Gobi deserts, witnessing the historical changes of Chinese civilization for thousands of years. It is the world-famous Great Wall. Today, we will take the camera to Jizhou District, Tianjin City, and walk into the Huangyaguan Great Wall, a majestic Great Wall pass surrounded by dangerous mountains. There is no hustle and bustle of modern cities here, only the sound of mountain wind passing through the city walls, and the history told by ancient bricks and stones. Viewed from a high altitude, the Great Wall looks like a giant dragon entrenched among the mountains, undulating and winding along the ridges. The towering watchtowers, thick city walls, and precipitous valleys together form a magnificent picture of the Great Wall in the northern mountains. It is not only a representative Great Wall site in Tianjin, but also an important part of the Great Wall defense system in the Ming Dynasty. There are not only dangerous military passes, but also unique ancient buildings, as well as the majestic and magnificent natural scenery of the Yanshan Mountains. When we climb up the city wall step by step along the ancient stone steps, what we see in front of us is not only the magnificent scenery of mountains and rivers, but also a history about defense, protection and civilization inheritance. So, what is the history of the Huangyaguan Great Wall? Why did the ancients build passes here? What geographical advantages does it rely on to become an important part of the Great Wall defense system? Next, let us approach the Huangyaguan Great Wall and start a journey through history and mountains and rivers.
