why Hong-Kong separated from China and when?
Answers
Hong Kong , officially the Hong Kong Special Administrative Region of the People's Republic of China, is a specially administered territory on the eastern side of the Pearl River estuary in southern China. With over 7.4 million people of various nationalities in a territory of 1,104 square kilometres (426 sq mi), Hong Kong is the fourth-most densely populated region in the world.
Hong Kong was formerly a colony of the British Empire, after Qing China ceded Hong Kong Island at the conclusion of the First Opium War in 1842. The colony expanded to the Kowloon Peninsula in 1860 after the Second Opium War and was further extended when Britain obtained a 99-year lease of the New Territories in 1898. The entire territory was returned to China when this lease expired in 1997. As a special administrative region, Hong Kong's system of government is separate from that in mainland China has resulted in a high level of atmospheric particulates.
Originally a lightly populated area of farming and fishing villages, the territory has become one of the most significant financial centres and trade ports in the world. It is the world's seventh-largest trading entity and its legal tender, the Hong Kong dollar, is the 13th-most traded currency. Although the city boasts one of the highest per capita incomes in the world, it suffers severe income inequality.
The territory features the largest number of skyscrapers in the world, most of them surrounding Victoria Harbour. Hong Kong ranks 7th on the UN Human Development Index and has the seventh-highest life expectancy in the world.[8] Over 90% of its population makes use of well-developed public transportation,[27] but air pollution from neighbouring industrial areas of mainland China has resulted in a high level of atmospheric particulates.
