Visit the Banchangyu Great Wall in autumn.

Standing on the top of the mountains, the Banchangyu Great Wall is surrounded by cliffs and steep slopes. It is both majestic like the first building in Beijing and steep like the Hanging Great Wall. It is both deep like a one-line sky and roaring like the Jiudaogang Waterfall... A feeling arises spontaneously, "Love my China, protect my Great Wall!" The Banchangyu Great Wall is located in the Haigang District of Qinhuangdao City, Hebei Province. It was built under the supervision of Qi Jiguang, a general of the Ming Dynasty. The Great Wall is generally 5 meters wide and 4.8 meters high (the height of the crenel is about 1.8 meters). It is built with stones and green bricks and stretches for about 15 kilometers. The terrain is dangerous, the architecture is majestic, and the enemy buildings are scattered. The highest enemy building is built on a mountain top more than 800 meters high.
