Hong Kong

The Hong Kong Special Administrative Region , commonly known as Hong Kong, is one of the two special administrative regions of the People's Republic of China, along with Macau. Comprising more than 260 islands, the territory is located on the eastern side of the Pearl River Delta, bordering Guangdong province in the north and facing the South China Sea in the east, west and south.
Hong Kong was a dependent territory of the United Kingdom from 1842 until the transfer of sovereignty to the People's Republic of China in 1997. The Sino-British Joint Declaration and the Basic Law of Hong Kong stipulate that Hong Kong operate with a high degree of autonomy until at least 2047, fifty years after the transfer. Under the policy of "one country, two systems", the Central People's Government is responsible for the territory's defense and foreign affairs, while Hong Kong maintains its own legal system based on English common law, police force, monetary system, customs policy, immigration policy, and delegates to international organisations and events.

Geography
Hong Kong primarily consists of Hong Kong Island, Lantau Island, Kowloon Peninsula and the New Territories. The Kowloon Peninsula is attached to the New Territories to the north, and the New Territories spans northwards eventually connecting with mainland China across the Sham Chun River (Shenzhen River). In total, Hong Kong encompasses a collection of 262 islands in the South China Sea, of which Lantau is the largest. Hong Kong Island is the second largest island and the most populated. Ap Lei Chau is the most densely populated island in the world.
The name "Hong Kong", literally meaning "fragrant harbour", is derived from the area around present-day Aberdeen on Hong Kong Island, where fragrant wood products and fragrant incense were once traded. The narrow body of water separating Hong Kong Island and Kowloon Peninsula, Victoria Harbour, is one of the deepest natural maritime ports in the world.
Despite Hong Kong's reputation of being intensely urbanised, the territory has made much effort to promote a green environment. Most of the territory remains undeveloped as the terrain is mostly hilly to mountainous with steep slopes. Of the territory's 1,104 square kilometres (426 square miles), less than 25% is developed. The remaining land is remarkably green with about 40% of landmass reserved as country parks and nature reserves. Most of the territory's urban development exists on Kowloon peninsula, along the northern shores of Hong Kong island and in scattered settlements throughout the New Territories.
Hong Kong's long, irregular and curvaceous coastline also affords the territory with many bays, rivers and beaches. Despite the territory's extensive wooded and ocean setting, environmental awareness is growing as Hong Kong's air ranks as one of the most polluted. Approximately 80% of the city's smog originates from other parts of the Pearl River Delta.
Hong Kong is 60 kilometres (37 miles) east of Macau on the opposite side of the Pearl River Delta and borders the city of Shenzhen in Guangdong Province to the north. The highest point in the territory is Tai Mo Shan, at a height of 958 metres (3,142 ft) above sea level. Lowlands exist in the northwestern part of the New Territories.
