Landforms Of Asia
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

State Council Information Office
The State Council Information Office (SCIO; ) is the chief information office of the State Council of the People's Republic of China. In 2014, SCIO was absorbed into the Central Propaganda Department of the Chinese Communist Party (CCP). History The SCIO was formed in 1991 when the CCP Central Committee made the External Propaganda Leading Group of the Propaganda Department of the Chinese Communist Party its own office. The office was created with the goal of improving the Chinese government's international image following the 1989 Tiananmen Square protests and massacre.

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the oldest form of i ...

CNKI
CNKI (China National Knowledge Infrastructure; ) is a private-owned publishing company in China since 2014. CNKI maintains high annual subscription fees due to its ''de facto'' monopoly status on journal search in China. Because its subscription fee raised sharply every year, many elite Chinese universities and research institutions, including the Chinese Academy of Sciences and Peking University, have stopped subscribing to CNKI. CNKI owns a system called "China Integrated Knowledge Resources System," including journals, doctoral dissertations, masters' theses, proceedings, newspapers, yearbooks, statistical yearbooks, e-books, patents and standards. In January 2013, CNKI became the second designated DOI agent in mainland China, after the Institute of Scientific and Technical Information of China under the Ministry of Science and Technology. In May 2022, the State Administration for Market Regulation of China launched an antitrust investigation into CNKI for anti-competitive ...

The southern slope of the Daba Mountains drains into the Sichuan Basin or directly into the Yangtze via short streams that flow into the river in the Three Gorges area, such as the Shen Nong Stream. The northern side drains into the Han River, a major tributary of the Yangtze, which, however, does not join the Yangtze until some hundreds kilometers to ...
