China (i/ˈtʃaɪnə/; Chinese: 中国; pinyin: Zhōngguó; see also Names of China), officially the People's Republic of China (PRC), is the world's most-populous country, with a population of over 1.3 billion. Covering approximately 9.6 million square kilometres, the East Asian state is the world's second-largest country by land area, and the third- or fourth-largest in total area, depending on the definition of total area.

Landscape and climate

The territory of China lies between latitudes 18° and 54° N, and longitudes 73° and 135° E. China's landscapes vary significantly across its vast width. In the east, along the shores of the Yellow Sea and the East China Sea, there are extensive and densely populated alluvial plains, while on the edges of the Inner Mongolian plateau in the north, broad grasslands predominate. Southern China is dominated by hills and low mountain ranges, while the central-east hosts the deltas of China's two major rivers, the Yellow River and the Yangtze River. Other major rivers include the Xi, Mekong,Brahmaputra and Amur. To the west, major mountain ranges, most notably the Himalayas, and high plateaus feature among the more arid landscapes of the north, such as the Taklamakan and the Gobi Desert. The world's highest point, Mt. Everest (8848m), lies on the Sino-Nepalese border. The country's lowest point, and the world's fourth-lowest, is the dried lake bed of Ayding Lake (−154m) in the Turpan Depression.

A major environmental issue in China is the continued expansion of its deserts, particularly the Gobi Desert, which is currently the world's fifth-largest desert.[93][94] Although barrier tree lines planted since the 1970s have reduced the frequency of sandstorms, prolonged drought and poor agricultural practices have resulted in dust storms plaguing northern China each spring, which then spread to other parts of East Asia, including Korea and Japan. According to China's environmental watchdog, Sepa, China is losing a million acres (4,000 km²) per year to desertification.[95] Water quality, erosion, and pollution control have become important issues in China's relations with other countries. Meltingglaciers in the Himalayas could potentially lead to water shortages for hundreds of millions of people.

China's climate is mainly dominated by dry seasons and wet monsoons, which lead to a pronounced temperature differences between winter and summer. In the winter, northern winds coming from high-latitude areas are cold and dry; in summer, southern winds from coastal areas at lower latitudes are warm and moist. The climate in China differs from region to region because of the country's extensive and complextopography.

China is one of 17 megadiverse countries, lying in two of the world's major ecozones: the Palearctic and the Indomalaya. In the Palearctic zone, mammals such as the horse, camel, tapir, and jerboa can be found. Among the species found in the Indomalaya region are the Leopard Cat, bamboo rat, treeshrew, and various monkey and ape species. Some overlap exists between the two regions due to natural dispersal and migration; deer, antelope, bears, wolves, pigs, and numerous rodent species can all be found in China's diverse climatic and geological environments. The famous giant panda is found only in a limited area along the Yangtze River. China suffers from a continuing problem with trade in endangered species, although there are now laws to prohibit such activities.

China also hosts a variety of forest types. Cold coniferous forests predominate in the north of the country, supporting animal species such as moose and the Asian black bear, along with over 120 bird species. Moist conifer forests can have thickets of bamboo as an understorey, replaced by rhododendrons in higher montane stands of juniper and yew. Subtropical forests, which dominate central and southern China, support as many as 146,000 species of flora. Tropical and seasonal rainforests, though confined to Yunnan andHainan Island, contain a quarter of all the plant and animal species found in China.

Culture

Since ancient times, Chinese culture has been heavily influenced by Confucianism and conservative philosophies. For much of the country's dynastic era, opportunities for social advancement could be provided by high performance in the prestigious Imperial examinations, which were instituted in 605 AD to help the Emperor select skilful bureaucrats. The literary emphasis of the exams affected the general perception of cultural refinement in China, such as the belief that calligraphy and literati painting were higher forms of art than dancing or drama.

A number of more authoritarian and rational strains of thought were also influential, with Legalism being a prominent example. There was often conflict between the philosophies – for instance, the individualistic Song Dynasty neo-Confucians believed that Legalism departed from the original spirit of Confucianism. Examinations and a culture of merit remain greatly valued in China today. In recent years, a number of New Confucians have claimed that modern democratic ideals and human rights are compatible with traditional Confucian values.

The first leaders of the People's Republic of China were born into the traditional imperial order, but were influenced by the May Fourth Movement and reformist ideals. They sought to change some traditional aspects of Chinese culture, such as rural land tenure, sexism, and the Confucian system of education, while preserving others, such as the family structure and culture of obedience to the state.

Some observers see the period following the establishment of the PRC in 1949 as a continuation of traditional Chinese dynastic history, while others claim that the Communist Party's rule has damaged the foundations of Chinese culture, especially through political movements such as the Cultural Revolution of the 1960s, where many aspects of traditional culture were destroyed, having been denounced as 'regressive and harmful' or 'vestiges of feudalism'. Many important aspects of traditional Chinese morals and culture, such as Confucianism, Chinese art, literature, and performing arts like Peking opera, were altered to conform to government policies and propaganda at the time.

Today, the Chinese government has accepted numerous elements of traditional Chinese culture as being integral to Chinese society. With the rise of Chinese nationalism and the end of the Cultural Revolution, various forms of traditional Chinese art, literature, music, film, fashion and architecture have seen a vigorous revival, and folk and variety art in particular have sparked interest nationally and even worldwide.

Prior to the beginning of maritime Sino-European trade in the 16th century, medieval China and the European West were linked by the Silk Road, which was a key route of cultural as well as economic exchange. Artifacts from the history of the Road, as well as from the natural history of the Gobi desert, are displayed in the Silk Route Museum in Jiuquan.

Cuisine

Chinese cuisine is highly diverse, drawing on several millennia of culinary history. The dynastic emperors of ancient China were known to host banquets with over 100 dishes served at a time, employing countless imperial kitchen staff and concubines to prepare the food. Such royal dishes gradually became a part of wider Chinese culture. China's staple food is rice, but the country is also well known for its meat dishes. Spices are endemic to Chinese cuisine.

Numerous foreign offshoots of Chinese food, such as Hong Kong cuisine and American Chinese food, have emerged in the various nations which play host to the Chinese diaspora.
