There is old saying goes in China, one who fails to reach the Great Wall is not a hero. Badaling Great Wall in Beijing is the best-preserved and most complete section. You should visit it at least once in your life.

It’s 7.5 miles (12 kilometers) with 43 watchtowers in this section all alongbutunfortunately, only 2.3 miles (3.74 kilometers) and 19 watchtowers have been restored and opened to the visitors.
In this section, the wall is about 26 feet (7.8 meters) tall, and 20 feet (6 meters) wide in average, which would allow five horses to gallop or ten soldiers to march abreast.
It is built of huge bar-stones and bricks. The interior of the wall is firm and solid because of the rammed earth and small stones in it.
