Hong Kong is one of two special administrative regions (SARs) of the People's Republic of China (PRC), the other being Macau. Situated on China's south coast and enclosed by the Pearl River Delta and South China Sea,it is renowned for its expansive skyline and deep natural harbour. With a land mass of 1,104 km2 (426 sq mi) and a population of seven million people, Hong Kong is one of the most densely populated areas in the world.Hong Kong's population is 95 percent ethnic Chinese and 5 percent from other groups.Hong Kong's Han Chinese majority originate mainly from the cities of Guangzhou and Taishan in the neighbouring Guangdong province.
Hong Kong became a colony of the British Empire after the First Opium War (1839-42). Originally confined to Hong Kong Island, the colony's boundaries were extended in stages to the Kowloon Peninsula and the New Territories by 1898. It was occupied by Japan during the Pacific War, after which the British resumed control until 1997, when China regained sovereignty.The region espoused minimum government intervention under the ethos of positive non interventionism during the colonial era.The time period greatly influenced the current culture of Hong Kong, often described as "East meets West",and the educational system, which used to loosely follow the system in England until reforms implemented in 2009.
Under the principle of "one country, two systems", Hong Kong has different political system from mainland China.Hong Kong's independent judiciary functions under the common law framework.The Basic Law of Hong Kong, its constitutional document, which stipulates that Hong Kong shall have a "high degree of autonomy" in all matters except foreign relations and military defence, governs its political system.Although it has a burgeoning multi party system, a small circle electorate controls half of its legislature. An 800 person Election Committee selects the Chief Executive of Hong Kong, the head of government.
As one of the world's leading international financial centres, Hong Kong has a major capitalist service economy characterised by low taxation and free trade, and the currency, Hong Kong dollar, is the ninth most traded currency in the world.The lack of space caused demand for denser constructions, which developed the city to a centre for modern architecture and the world's most vertical city.The dense space also led to a highly developed transportation network with public transport travelling rate exceeding 90 percent,the highest in the world.
