Do you know the Great Wall of China spans some 3,500 km across China and was created over a period of 1,800 years from the 3rd Century BC?

Look at the wall section of the Great Wall of China. It’s amazing!

A Wall? A 3500km in length WALL?!! I rather say it's a highway construction... It's 3.6 times of our North-South Highway! Haha..
