A UNESCO World Heritage Site: The Great Wall of China.
A series of fortifications built to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe. The entire wall with all of its branches measures out to be 21,196 km (13,171 mi). Today, the Great Wall is generally recognized as one of the most impressive architectural feats in history.

Beijing is approximately at the same latitude as Philadelphia in the U.S. (but drier in winter and much wetter in summer) and Madrid in Spain (though colder in winter).
Beijing’s air pollution and traffic congestion are being tackled with improved public transport, restrictions on the use of vehicles, and the relocation of factories. Daily and localized variations in airborne particle levels are great, with some days below the WHO’s strictest targets. Breathing Beijing’s air for six average days is the equivalent of smoking just one cigarette, which is not bad for a large developing world city.
Beijing’s air quality, apart from pollutants, is greatly affected by occasional dust storms in the spring, and humidity contributes greatly to the haze in summer, which is the worst time of the year for visibility and air quality. Shutterbugs will probably find an autumn trip best for photography.
