How many landforms are there in China? What is the terrain of Mutianyu Great Wall?

On the vast land of China, there are majestic plateaus, undulating mountains, vast plains and low hills, and large and small basins surrounded by mountains and low in the middle. There are five basic landforms on land.

Most of the Great Wall is built on mountains. Mutianyu was originally a small mountain village, located in Beixinying Township, Huairou District (now Bohai Town), where the mountains are undulating and the trees are lush. The Great Wall of Wan Li winds from southeast to northwest at the top of the mountain. The mountains here are gentle and steep, and the curves and straights alternate, so it is very stereoscopic. Mutianyu is known as the "Xiongguan of Dangerous Ridge" because of its very important geographical position, and Mutianyu Pass is one of the important passes for the Ming Dynasty to support the capital, and it is also the location of the Ming Dynasty's ancestral mausoleum, and there have been many wars. Mutianyu Great Wall connects Juyongguan in the west and Gubeikou in the east, which is the eastern section of huanghua town, the north gate of Beijing. Mutianyu Great Wall has been called the northern barrier to guard the capital and the imperial tomb since ancient times, and Mutianyu Pass is one of the important passes to support the capital and the imperial tomb in Ming Dynasty.

Geographically speaking, strictly speaking, the mountains are all above 500 meters above sea level. Mutianyu Pass is only 486 meters above sea level.
