Hanoi vs Oak

Informations

Hanoi (UK: ha-, hə-NOY or US: hah-NOY; Vietnamese: Hà Nội [hàː nôjˀ] (listen)) is the capital city of Vietnam. It covers an area of 3,358.6 km2 (1,296.8 sq mi). It is the second largest city in Vietnam, with over eight million residents within the city proper and an estimated population of 20 million within the metropolitan area. Located in part of the Red River Delta, Hanoi is the commercial, cultural, and educational centre of Northern Vietnam. Having an estimated nominal GDP of US$32.8 billion as of 2018, it is the second most productive economic area of Vietnam, after Ho Chi Minh City. The city is a settlement along the banks of the Red River. In 257 B.C, under the rule of king An Dương Vương, the citadel of Cổ Loa, nowaday Đông Anh district of Hanoi, was constructed and served as the capital of Âu Lạc. After the fall of Âu Lạc, the city was renamed to Tống Bình and ultimately Đại La. In 1010, emperor Lý Thái Tổ moved the capital to Đại La, renaming it Thăng Long (literally "Ascending Dragon"). Thăng Long would remain the political and cultural centre of the state of Đại Việt until 1802, when the Nguyễn dynasty, the last imperial dynasty of Vietnam, moved the capital to Huế.

The city renamed to Hanoi in 1831, and was the capital of French Indochina from 1883 to 1945. On 6 January 1946, the National Assembly of the Democratic Republic of Vietnam designated Hanoi as the capital of the newly-independent country, which would last during the First Indochina War (1946–1954) and the Vietnam War (1955–1975). Hanoi has been the capital of the Socialist Republic of Vietnam since 1976. Historically it had Chinese, French and Russian influences. It hosts various venerable educational institutions and cultural venues of significance, including the Vietnam National University, the Mỹ Đình National Stadium, and the Vietnam National Museum of Fine Arts. On 16 July 1999, the UNESCO presented the title "City for Peace" to Hanoi. Hanoi joined UNESCO's Network of Creative Cities as a Design City on 31 October 2019 on the occasion of World Cities' Day.

An oak is a tree or shrub in the genus Quercus (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus (stone oaks), as well as in those of unrelated species such as Grevillea robusta (silky oaks) and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.

Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small female flowers, meaning that the trees are monoecious. The fruit is a nut called an acorn or oak nut borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on their species. The acorns and leaves contain tannic acid, which helps to guard from fungi and insects. The live oaks are distinguished for being evergreen, but are not actually a distinct group and instead are dispersed across the genus.
