Like a gigantic dragon, the Great Wall winds across deserts, grasslands, mountains and plateaus, stretching from the east to west of China. It was continuously built from the 3rd century BC to the 17th century AD on the northern border of the country as a military defense project of successive Chinese dynasties, with a total length of more than 20,000 kilometers.

With a history of more than 2,000 years, some sections are now in ruins or have disappeared entirely. However, it is still one of the most appealing attractions in the world due to its architectural grandeur and historical significance.
