Oak vs Wuhan

Informations

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.

Wuhan (simplified Chinese: 武汉; traditional Chinese: 武漢, [ù.xân] (listen)) is the capital of Hubei Province in the People's Republic of China. It is the largest city in Hubei and the most populous city in Central China, with a population of over 11 million, the ninth-most populous Chinese city and one of the nine National Central Cities of China.The name "Wuhan" came from the city's historical origin from the conglomeration of Wuchang, Hankou and Hanyang, which are collectively known as the "Three Towns of Wuhan" (武汉三镇). It lies in the eastern Jianghan Plain, at the confluence of the Yangtze river and its largest tributary, the Han River and is known as "Nine Provinces' Thoroughfare" (九省通衢).Wuhan is considered by some to be one of the potential sites of the pivotal Battle of the Red Cliffs, which stopped warlord Cao Cao's incursion into southern China at the end of the Eastern Han dynasty. Other historical events taking place in Wuhan include the Wuchang Uprising of 1911, which led to the downfall of the Qing dynasty and the establishment of the Republic of China. Wuhan was briefly the capital of China in 1927 under the left wing of the Kuomintang (KMT) government led by Wang Jingwei. The city later served as the wartime capital of China for ten months in 1937 during the Second Sino-Japanese War. SARS-CoV-2, a novel coronavirus that caused the COVID-19 pandemic, was first identified in Wuhan in December 2019.Wuhan is considered the political, economic, financial, commercial, cultural and educational center of Central China. It is a major transportation hub, with dozens of railways, roads and expressways passing through the city and connecting to other major cities. Because of its key role in domestic transportation, Wuhan is sometimes referred to as "the Chicago of China" by foreign sources.

The "Golden Waterway" of the Yangtze River and the Han River traverse the urban area and divide Wuhan into the three districts of Wuchang, Hankou and Hanyang. The Wuhan Yangtze River Bridge crosses the Yangtze in the city. The Three Gorges Dam, the world's largest power station in terms of installed capacity, is located nearby. Historically, Wuhan has suffered risks of flooding, prompting the government to alleviate the situation by introducing ecologically friendly absorption mechanisms.While Wuhan has been a traditional manufacturing hub for decades, it is also one of the areas promoting modern industrial changes in China. Wuhan consists of three national development zones, four scientific and technological development parks, over 350 research institutes, 1,656 high tech enterprises, numerous enterprise incubators and investments from 230 Fortune Global 500 firms. It produced GDP of US$22.4 billion in 2018. The Dongfeng Motor Corporation, an automobile manufacturer, is headquartered in Wuhan. The city is home to multiple notable institutes of higher education, including Wuhan University and the Huazhong University of Science and Technology. Wuhan is also one of the top city in the world by scientific research and it ranks 13th globally and 4th in China (after Beijing, Shanghai and Nanjing). In 2017, Wuhan was designated as a Creative City by UNESCO, in the field of design. Wuhan is classified as a Beta- (global second tier) city together with other 7 cities in China, including Changsha, Dalian, Jinan, Shenyang, Xiamen, Xi'an and Zhengzhou by the Globalization and World Cities Research Network.
