Grand Canal (China)
–
The Grand Canal, a UNESCO World Heritage Site, is the longest canal or artificial river in the world and a famous tourist destination. Starting at Beijing, it passes through Tianjin and the provinces of Hebei, Shandong, Jiangsu and Zhejiang to the city of Hangzhou, linking the Yellow River and Yangtze River. The oldest parts of the date back to the 5th century BC. The total length of the Grand Canal is 1,776 km and its greatest height is reached in the mountains of Shandong, at a summit of 42 m. The canal has been admired by many throughout history including Japanese monk Ennin, Persian historian Rashid al-Din, Korean official Choe Bu, historically, periodic flooding of the adjacent Yellow River threatened the safety and functioning of the canal. During wartime the high dikes of the Yellow River were sometimes deliberately broken in order to flood advancing enemy troops and this caused disaster and prolonged economic hardships. Despite temporary periods of desolation and disuse, the Grand Canal furthered an indigenous and it has allowed faster trading and has improved Chinas economy. The southern portion remains in constant heavy use to the present day, in the late Spring and Autumn period, King Fuchai of Wu, ruler of the State of Wu, ventured north to conquer the neighboring State of Qi. He ordered a canal be constructed for trading purposes, as well as a means to ship ample supplies north in case his forces should engage the northern states of Song and this canal became known as the Han Gou. Han Gou is known as the second oldest section of the later Grand Canal since the Hong Gou most likely preceded it and it linked the Yellow River near Kaifeng to the Si and Bian rivers and became the model for the shape of the Grand Canal in the north. The exact date of the Hong Gous construction is uncertain, it is first mentioned by the diplomat Su Qin in 330 BC when discussing state boundaries. The historian Sima Qian dated it much earlier than the 4th century BC, attributing it to the work of Yu the Great and its main role throughout its history was the transport of grain to the capital. By the year 600, there were major build ups of silt on the bottom of the Hong Gou canal, obstructing river barges whose drafts were too deep for its waters. The chief engineer of the Sui dynasty, Yuwen Kai, advised the dredging of a new canal that would run parallel to the existing canal, diverging from it at Chenliu. The new canal was to pass not Xuzhou but Suzhou, to connecting with the Si River. With the recorded labor of five men and women under the supervision of Ma Shumou. The Grand Canal was fully completed under the second Sui emperor, from the years 604 to 609, first by linking Luoyang to the Yangzhou, then expanding it to Hangzhou and this allowed the southern area to provide grain to the northern province, particularly to troops stationed there. Running alongside and parallel to the canal was an imperial roadway, the government also planted an enormous line of trees

Yellow River
–
The Yellow River or Huang He is the second-longest river in Asia, following the Yangtze River, and the sixth-longest river system in the world at the estimated length of 5,464 km. Originating in the Bayan Har Mountains in Qinghai province of western China, it flows through nine provinces, the Yellow River basin has an east–west extent of about 1,900 kilometers and a north–south extent of about 1,100 km. Its total basin area is about 742,443 square kilometers and its basin was the birthplace of ancient Chinese civilization, and it was the most prosperous region in early Chinese history. Early Chinese literature including the Yu Gong or Tribute of Yu dating to the Warring States period refers to the Yellow River as simply 河, the first appearance of the name 黃河 is in the Book of Han written during the Eastern Han dynasty about the Western Han dynasty. The adjective yellow describes the color of the muddy water in the lower course of the river. One of its older Mongolian names was the Black River, because the river runs clear before it enters the Loess Plateau, in Mongolia itself, it is simply called the Šar Mörön. In Qinghai, the rivers Tibetan name is River of the Peacock above sea level they are the two largest plateau freshwater lakes nationwide, flowing east at the eastern edge of the Amne Machin Mountains, the Yellow River enters Maqu County in Gansu. Here, the river skirts through the peat bog known as the Zoigê Wetlands. Flowing now along the edge of Amne Machin, the river reenters Qinghai. The valley section stretches from Longyang Gorge in Qinghai to Qingtong Gorge in Gansu, steep cliffs line both sides of the river. The water bed is narrow and the drop is large, so the flow in this section is extremely turbulent. There are 20 gorges in this section, the most famous of these being the Longyang, Jishi, Liujia, Bapan, the flow conditions in this section makes it the best location for hydroelectric plants. The Yellow River exits Qinghai for the second and final time in these gorges, downstream from the Yanguo Gorge, the provincial capital of Lanzhou is built upon the Yellow Rivers banks. The Yellow River flows northeasterly out of Gansu and into Ningxia before the Qingtong Gorge, after emerging from the Qingtong Gorge, the river comes into a section of vast alluvial plains, the Yinchuan Plain and Hetao Plain. In this section, the regions along the river are mostly deserts and grasslands, the Hetao Plain has a length of 900 km and width of 30 to 50 km. It is historically the most important irrigation plain along the Yellow River, the Ordos Loop formed by an enormous twist of the Yellow River, beginning at Zhongning County in Ningxia and ending with a drastic eastward turn at its confluence with the Wei at Tongguan in Shaanxi. However, the division for the middle reaches of the river run from Hekou in Togtoh County, Inner Mongolia, to Zhengzhou.

Boxer Rebellion
–
The Boxer Rebellion, Boxer Uprising or Yihequan Movement a violent anti-foreign and anti-Christian uprising that took place in China between 1899 and 1901, towards the end of the Qing dynasty. The uprising took place against a background of severe drought and the disruption caused by the growth of foreign spheres of influence, Foreigners and Chinese Christians sought refuge in the Legation Quarter. Diplomats, foreign civilians and soldiers as well as Chinese Christians in the Legation Quarter were placed under siege by the Imperial Army of China, Chinese officialdom was split between those supporting the Boxers and those favoring conciliation, led by Prince Qing. The supreme commander of the Chinese forces, the Manchu General Ronglu, the Eight-Nation Alliance, after being initially turned back, brought 20,000 armed troops to China, defeated the Imperial Army, and captured Beijing on August 14, lifting the siege of the Legations. Uncontrolled plunder of the capital and the surrounding countryside ensued, along with the execution of those suspected of being Boxers. The Empress Dowager then sponsored a set of institutional and fiscal changes in an attempt to save the dynasty by reforming it. The Righteous and Harmonious Fists arose in the sections of the northern coastal province of Shandong long known for social unrest, religious sects. American Christian missionaries were probably the first to refer to the well-trained, athletic men as Boxers, because of the martial arts. Their primary practice was a type of possession which involved the whirling of swords, violent prostrations. The opportunities to fight back Western encroachment and colonization were especially attractive to unemployed village men, the tradition of possession and invulnerability went back several hundred years but took on special meaning against the powerful new weapons of the West. The Boxers, armed with rifles and swords, claimed supernatural invulnerability towards blows of cannon, rifle shots, furthermore, the Boxer groups popularly claimed that millions of soldiers of Heaven would descend to assist them in purifying China of foreign oppression. The Big Swords, emboldened by this support, also attacked their local Catholic village rivals. The Big Swords responded by attacking Catholic churches and burning them, the line between Christians and bandits, remarks one recent historian, became increasingly indistinct. As a result of pressure in the capital, Yuxian executed several Big Sword leaders. More martial secret societies started emerging after this, the early years saw a variety of village activities, not a broad movement or a united purpose. Martial folk religious societies such as the Baguadao prepared the way for the Boxers, like the Red Boxing school or the Plum Flower Boxers, the Boxers of Shandong were more concerned with traditional social and moral values, such as filial piety, than with foreign influences. One leader, for instance, Zhu Hongdeng, started as a healer, specializing in skin ulcers. Zhu claimed descent from Ming dynasty emperors, since his surname was the surname of the Ming imperial family and he announced that his goal was to Revive the Qing and destroy the foreigners

Naval mine
–
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, Naval mines can be used offensively—to hamper enemy shipping movements or lock vessels into a harbour, or defensively—to protect friendly vessels and create safe zones. Mines can be laid in many ways, by purpose-built minelayers, refitted ships, submarines and their flexibility and cost-effectiveness make mines attractive to the less powerful belligerent in asymmetric warfare. The cost of producing and laying a mine is usually anywhere from 0. 5% to 10% of the cost of removing it, parts of some World War II naval minefields still exist because they are too extensive and expensive to clear. It is possible for some of these 1940s-era mines to remain dangerous for many years to come, Mines have been employed as offensive or defensive weapons in rivers, lakes, estuaries, seas, and oceans, but they can also be used as tools of psychological warfare. Offensive mines are placed in enemy waters, outside harbours and across important shipping routes with the aim of sinking both merchant and military vessels. Defensive minefields safeguard key stretches of coast from enemy ships and submarines, forcing them into more easily defended areas, minefields designed for psychological effect are usually placed on trade routes and are used to stop shipping from reaching an enemy nation. They are often spread thinly, to create an impression of minefields existing across large areas, a single mine inserted strategically on a shipping route can stop maritime movements for days while the entire area is swept. International law requires nations to declare when they mine an area, the warnings do not have to be specific, for example, during World War II, Britain declared simply that it had mined the English Channel, North Sea, and French coast.
