Karst (/kɑːrst/) is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions.

Subterranean drainage may limit surface water, with few if any rivers or lakes. In regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground.

Tower karst are tall rock structures made up of soluble rock such as limestone. Tower karst forms as near-vertical joints and fractures are eroded downward by solution, leaving parts of a previously coherent rock mass isolated from each other. Tower karst is most common in tropical regions, although it may form in other climates as well.

Examples include Khao Phing Kan, also known as James Bond Island, in Thailand, and Cat Ba Island in Vietnam.

Guangxi, officially the Guangxi Zhuang Autonomous Region, is an autonomous region of the People's Republic of China, located in South China and bordering Vietnam (Tuyên Quang, Cao Bằng, Lạng Sơn, and Quảng Ninh Provinces) and the Gulf of Tonkin. Formerly a province, Guangxi became an autonomous region in 1958. Its current capital is Nanning.

Guangxi's location, in mountainous terrain in the far south of China, has placed it on the frontier of Chinese civilization throughout much of Chinese history. The current name "Guang" means "expanse" and has been associated with the region since the creation of Guang Prefecture in 226 AD. It was given provincial level status during the Yuan dynasty, but even into the 20th century, it was considered an open, wild territory. The abbreviation of the region (Chinese: 桂; Hanyu pinyin: Guì; Zhuang: Gvei) comes from the name of the city of Guilin, the provincial capital during both the Ming and Qing dynasties.

Ma Junwu (Chinese: 馬君武; 1881 in Guilin – 1940 in Guilin) was a scientist and educator in China and first president of Guangxi University.

The Eighth Route Army (simplified Chinese: 八路军; traditional Chinese: 八路軍; pinyin: Bālù-Jūn), also known as the 18th Group Army, was a group army nominally under the banner of the National Revolutionary Army (NRA) of the Republic of China, established in 1937 as part of the Second United Front against Japan. In practice, the Eighth Route Army was under the exclusive command of the Chinese Communist Party (CCP) and operated independently of the Kuomintang (KMT) central military command. Unlike most NRA units, which were directly overseen by the Nationalist Government, the Eighth Route Army maintained separate political and operational structures aligned with CCP objectives.

The Eighth Route Army was created from the Chinese Red Army on September 22, 1937, when the Chinese Communists and Chinese Nationalists formed the Second United Front against Japan at the outbreak of the Second Sino-Japanese War, as the Chinese theater was known in World War II. Together with the New Fourth Army, the Eighth Route Army formed the main Communist fighting force during the war and was commanded by Communist party leader Mao Zedong and general Zhu De. Though officially designated the 18th Group Army by the Nationalists, the unit was referred to by the Chinese Communists and Japanese military as the Eighth Route Army. The Eighth Route Army wore Nationalist uniforms and flew the flag of the Republic of China and waged mostly guerrilla war against the Japanese, collaborationist forces and, later in the war, other Nationalist forces. The unit was renamed the People's Liberation Army in 1947, after the end of World War II, as the Chinese Communists and Nationalists resumed the Chinese Civil War.

Osmanthus fragrans (lit. 'fragrant osmanthus') is a species of flowering plant in the family Oleaceae.
