Great Wall at Mutianyu
Located in the mountains 75 kilometers northeast of Beijing downtown, Mutianyu Great Wall was first built in Northern Qi Dynasty (550 - 557 A.D.). In the Ming Dynasty (1368 - 1644), Qi Jiguang, a famous patriotic general, strengthened it by adding more bricks instead of clay to make it solid. Therefore it once served as the northern protective screen for many years.
Despite the 22 watch towers built at regular intervals along the wall, a beacon tower is set up outside the Great Wall to alert(with rising smoke) other army service stations at the villages along the Wall.

What's more, a frozen waterfall with bushes on the hills is a view that you would not want to miss.
