Hong Kon, officially the Hong Kong Special Administrative Region of the People's Republic of China, is a special administrative region on the eastern side of the Pearl River estuary in southern China. With over 7.4 million people of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is the world's fourth most densely populated region.

Hong Kong became a colony of the British Empire after Qing China ceded Hong Kong Island at the end 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 territory was returned to China when the lease expired in 1997. As a special administrative region, Hong Kong's system of government is separate from that of mainland China and its people overwhelmingly identify as Hongkongers rather than Chinese.

Originally a sparsely populated area of farming and fishing villages, the territory has become one of the world's most significant financial centres and commercial ports. It is the world's seventh-largest trading entity, and its legal tender (the Hong Kong dollar) is the world's 13th-most-traded currency. Although the city has one of the highest per capita incomes in the world, it has severe income inequality.

The territory has the largest number of skyscrapers in the world, most surrounding Victoria Harbour. Hong Kong ranks seventh on the UN Human Development Index, and has the sixth-longest life expectancy in the world. Although over 90 per cent of its population uses public transportation, air pollution from neighbouring industrial areas of mainland China has resulted in a high level of atmospheric particulates.

Da Nang is the fifth largest city in Vietnam after Ho Chi Minh City, Hanoi, Haiphong and Can Tho in terms of urbanization and economy. Located on the coast of the South China Sea at the mouth of the Han River, it is one of Vietnam's most important port cities. As one of the country's five direct-controlled municipalities, it is under the direct administration of the central government.

Da Nang is the commercial and educational centre of Central Vietnam, as well as being the largest city in the region. In addition to its well-sheltered, easily accessible port, Da Nang's location on the path of National Route 1A and the North–South Railway makes it a hub for transportation. It is located within 100 km (62 mi) of several UNESCO World Heritage Sites, including the Imperial City of Hue, the Old Town of Hoi An, and the My Son ruins. The city was previously known as Cửa Hàn during early Đại Việt settlement, and as Tourane (or Turon) during French colonial rule. Before 1997, the city was part of Quang Nam-Da Nang Province.

On 1 January 1997, Da Nang was separated from Quảng Nam Province to become one of four independent (centrally controlled) municipalities in Vietnam. Da Nang is listed as a first class city, and has a higher urbanization ratio than any of Vietnam's other provinces or centrally governed cities.

Nha Trang is a coastal city and capital of Khánh Hòa Province, on the South Central Coast of Vietnam. It is bounded on the north by Ninh Hoà district, on the south by Cam Ranh town and on the west by Diên Khánh District. The city has about 392,000 inhabitants, a number that is projected to increase to 560,000 by 2015 and 630,000 inhabitants by 2025. An area of 12.87 square kilometres (4.97 sq mi) of the western communes of Diên An and Diên Toàn is planned to be merged into Nha Trang which will make its new area 265.47 square kilometres (102.50 sq mi) based on the approval of the Prime Minister of Vietnam in September 2012.

Nha Trang is well known for its beaches and scuba diving and has developed into a popular destination for international tourists, attracting large numbers of backpackers, as well as more affluent travelers on the south-east Asia circuit; it is already very popular with Vietnamese tourists, with Nha Trang Bay widely considered as among the world's most beautiful bays. Tourists are welcomed to participate in the Sea Festival, held biennially. Nha Trang was the site of the Miss Universe 2008 Pageant on July 14, 2008 and Miss Earth 2010 was held on December 4, 2010. It was also the site for the April 14, 2015 season 8 finale of Face Off. Nha Trang was approved to host the 2016 Asian Beach Games.

Historically, the city was known as Kauthara under the Champa. The city is still home to the famous Po Nagar Tower built by the Champa. Being a coastal city, Nha Trang is a centre for marine science based at the Nha Trang Oceanography Institute. The Hon Mun marine protected area is one of four first marine protected areas in the world admitted by the IUCN.
