China is commonly associated with many things including the Great Wall of China, their family planning policy, their population and the concentration of power in the Communist Party of China.
China, officially known as the People's Republic of China, is a sovereign state located in East Asia. As of 2014, it is the most populated country in the world, with a population that exceeds 1.35 billion. Its capital city is Beijing.
The Great Wall of China is a series of fortifications made of earth, stone, brick, wood and other materials mostly constructed along an east-to-west line across the historical northern borders of China. It was built to protect the Chinese Empire against encroachment by any unwanted persons. The construction of various walls started as early as the 7th century B.C. These walls, eventually connected and reinforced, are now collectively referred to as the Great Wall. A section of the wall that was built some time between 220 to 206 B.C. by the premier Emperor of China, Qin Shi Huang, is especially famous, although little of it remains in 2014.
The family planning policy, popularly called the "one-child policy" in the West, is a population control policy of the People's Republic of China. Approximately 35.9 percent of the Chinese population was subject to the one-child restriction in 2007. The policy was adopted in 1979 to mitigate social, economic and environmental problems in China.
