The best engineering works ever. It is the great wall of China. Kings of China had build it to protect an invasion of the northern race. It was entered as a World Heritage by UNESCO in 1987. It's almost 6000 kilometers from east to west of China and rises to a height of over 9 meters.
The great wall of China is not a simple wall. It's a military enemy line of defense and a cultural boundary. Also, it's regarded as one of the Seven Wonders of the World
I want to go to the great wall of China. It's really long and long. If I go to China, I will go this place at my first time in China.
