Hanoi (/hæˈnɔɪ/ or US /həˈnɔɪ/; Vietnamese: Hà Nội [ha˨˩ nɔj˩]) is the capital of Vietnam and the country's second largest city. Its population in 2009 was estimated at 2.6 million for urban districts and 7 million for the metropolitan jurisdiction. The number of population in 2015 was estimated at 7.7 million people. From 1010 until 1802, it was the most important political centre of Vietnam. It was eclipsed by Huế, the imperial capital of Vietnam during the Nguyễn Dynasty (1802–1945), but Hanoi served as the capital of French Indochina from 1902 to 1954. From 1954 to 1976, it was the capital of North Vietnam, and it became the capital of a reunified Vietnam in 1976, after the North's victory in the Vietnam War.

The city lies on the right bank of the Red River. Hanoi is 1,760 km (1,090 mi) north of Ho Chi Minh City and 120 km (75 mi) west of Hai Phong city.

October 2010 officially marked 1000 years since the establishment of the city. The Hanoi Ceramic Mosaic Mural is a 4 km ceramic mosaic mural created to mark the occasion.

Sun

The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.About three quarters of the Sun's mass consists of hydrogen; the rest is mostly helium, with much smaller quantities of heavier elements, including oxygen, carbon, neon and iron.

The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became increasingly hot and dense, eventually initiating nuclear fusion in its core. It is thought that almost all stars form by this process.

Vietnamese language

Vietnamese ⁱ/ˌviɛtnəˈmiːz/ (tiếng Việt) is an Austroasiatic language that originated in the north of Vietnam and is the national and official language of the country. It is the native language of the Vietnamese (Kinh) people, as well as a first or second language for the many ethnic minorities of Vietnam. As the result of Vietnamese emigration and cultural influence, Vietnamese speakers are found throughout the world, notably in East and Southeast Asia, North America, Australia and Western Europe. Vietnamese has also been officially recognized as a minority language in the Czech Republic.

It is part of the Austroasiatic language family of which it has by far the most speakers (several times as many as the other Austroasiatic languages combined). Vietnamese vocabulary has borrowings from Chinese, and it formerly used a modified set of Chinese characters called chữ nôm given vernacular pronunciation. The Vietnamese alphabet (quốc ngữ) in use today is a Latin alphabet with additional diacritics for tones, and certain letters.

West Lake

West Lake (Chinese: 西湖, Xī Hú) is a freshwater lake in Hangzhou, the capital of Zhejiang province in eastern China. It is divided into five sections by three causeways. There are numerous temples, pagodas, gardens, and artificial islands within the lake.

West Lake has influenced poets and painters throughout Chinese history for its natural beauty and historic relics, and it has also been among the most important sources of inspiration for Chinese garden designers. It was made a UNESCO World Heritage Site in 2011, described as having "influenced garden design in the rest of China as well as Japan and Korea over the centuries" and reflecting "an idealized fusion between humans and nature".

Vietnam (UK /ˌvjɛtˈnæm, -ˈnɑːm/, US ⁱ/ˌviːətˈnɑːm, -ˈnæm/;Vietnamese: Việt Nam [viət˨ næm˧]), officially the Socialist Republic of Vietnam (SRV; Vietnamese: Cộng Hòa Xã Hội Chủ Nghĩa Việt Nam ( listen)), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.5 million inhabitants as of 2014, it is the world's 14th-most-populous country, and the eighth-most-populous Asian country. The name Vietnam translates as "Southern Viet" (synonymous with the much older term Nam Viet); it was first officially adopted in 1802 by Emperor Gia Long, and was adopted again in 1945 with the founding of the Democratic Republic of Vietnam under Ho Chi Minh. The country is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, and Malaysia across the South China Sea to the southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1975.
