Three Kingdoms
The Three Kingdoms () from 220 to 280 AD was the tripartite division of China among the dynastic states of Cao Wei, Shu Han, and Eastern Wu. The Three Kingdoms period was preceded by the Han dynasty#Eastern Han, Eastern Han dynasty and was followed by the Jin dynasty (266–420), Western Jin dynasty. The short-lived state of Yan (Three Kingdoms), Yan on the Liaodong Peninsula, which lasted from 237 to 238, is sometimes considered as a "4th kingdom". Academically, the period of the Three Kingdoms refers to the period between the establishment of Cao Wei in 220 and the Conquest of Wu by Jin, conquest of the Eastern Wu by the Western Jin in 280. The earlier, "unofficial" part of the period, from 184 to 220, was marked by chaotic infighting between warlords in various parts of China during the end of the Han dynasty, downfall of the Eastern Han dynasty. The middle part of the period, from 220 to 263, was marked by a more militarily stable arrangement between three rival states ...

Chancellor (China)
The grand chancellor (''zaixiang, tsai-hsiang''), also translated as counselor-in-chief, chancellor, chief councillor, chief minister, imperial chancellor, lieutenant chancellor and prime minister, was the highest-ranking executive official in the imperial Chinese government. The term was known by many different names throughout Chinese history, and the exact extent of the powers associated with the position fluctuated greatly, even during a particular dynasty. During the Six Dynasties period, the term denoted a number of power-holders serving as chief administrators, including ''zhongshun jian'' (Inspector General of the Secretariat), ''zhongshu ling'' (President of the Secretariat), ''shizhong'' (Palace Attendant), ''shangshu ling'' and ''puye'' (president and vice-president of the Department of State Affairs). History In the Spring and Autumn period, Guan Zhong was the first chancellor in China, who became chancellor under the state of Qi in 685 BC. In Qin, during the Warring ...

Romance Of The Three Kingdoms
''Romance of the Three Kingdoms'' () is a 14th-century historical novel attributed to Luo Guanzhong. It is set in the turbulent years towards the end of the Han dynasty and the Three Kingdoms period in Chinese history, starting in 184 AD and ending with the reunification of the land in 280 by Western Jin. The novel is based primarily on the ''Records of the Three Kingdoms'' (), written by Chen Shou. The story – part historical and part fictional – romanticises and dramatises the lives of feudal lords and their retainers, who tried to replace the dwindling Han dynasty or restore it. While the novel follows hundreds of characters, the focus is mainly on the three power blocs that emerged from the remnants of the Han dynasty, and would eventually form the three states of Cao Wei, Shu Han, and Eastern Wu. The novel deals with the plots, personal and military battles, intrigues, and struggles of these states to achieve dominance for almost 100 years. ''Romance of the Three Kin ...

Luo Guanzhong
Luo Ben (c. 1330–1400, or c.1280–1360), better known by his courtesy name Guanzhong (Mandarin pronunciation: ), was a Chinese writer who lived during the Ming dynasty. He was also known by his pseudonym Huhai Sanren (). Luo was attributed with writing ''Romance of the Three Kingdoms'', one of the Four Great Classical Novels of Chinese literature. Identity The location and date of Luo's birth are controversial. One possibility was that he was from Taiyuan, and lived in the late Yuan dynasty and early Ming dynasty by the record of his contemporary, the playwright Jia Zhongming (賈仲明), who said that he had met him in 1364. Another possibility was that he was born in Dongping County, Dongyuan, the province of Shandong, in about 1280 – 1360. Literary historians suggest other possibilities for his home, also including Hangzhou and Jiangnan. According to Meng Fanren (孟繁仁), Luo can be identified in the pedigree of the Luo family, and Taiyuan is most likely his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel mak ...

South-pointing Chariot
The south-pointing chariot (or carriage) was an ancient Chinese two-wheeled vehicle that carried a movable pointer to indicate the south, no matter how the chariot turned. Usually, the pointer took the form of a doll or figure with an outstretched arm. The chariot was supposedly used as a compass for navigation and may also have had other purposes. The ancient Chinese invented a mobile-like armored cart in the 5th century BC called the Dongwu Che (). It was used for the purpose of protecting warriors on the battlefield. The Chinese war wagon was designed as a kind of mobile protective cart with a shed-like roof. It would serve to be rolled up to city fortifications to provide protection for sappers digging underneath to weaken a wall's foundation. The early Chinese war wagon became the basis of technologies for the making of ancient Chinese south-pointing chariots. There are legends of earlier south-pointing chariots, but the first reliably documented one was created by the Chi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chain Pump
The chain pump is type of a water pump in which several circular discs are positioned on an endless chain. One part of the chain dips into the water, and the chain runs through a tube, slightly bigger than the diameter of the discs. As the chain is drawn up the tube, water becomes trapped between the discs and is lifted to and discharged at the top. Chain pumps were used for centuries in the ancient Middle East, Europe, and China. In the Near East and Europe The earliest evidence for this device is in a Babylonian text from about 700 B.C. They were commonly powered by humans or animals. The device then appeared in ancient Egypt from about 200 B.C., featuring a pair of gear-wheels. A version of the chain pump was used in Ancient Greek and Roman, sometimes with pots, or scoops fixed to the chain, which, as they passed over the top pulley, tipped the water out; a 2nd century example is preserved in London. Philo of Byzantium wrote of such a device in the 2nd century B.C.; the histori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cao Rui
Cao Rui () (204 or 206 – 22 January 239), courtesy name Yuanzhong, was the second emperor of the state of Cao Wei during the Three Kingdoms period. His parentage is in dispute: his mother, Lady Zhen, was Yuan Xi's wife, but she later remarried Cao Pi, the first ruler of Wei. Based on conflicting accounts of his age, Pei Songzhi calculated that, in order to be Cao Pi's son, Cao Rui could not have been 33 (by East Asian age reckoning) when he died as recorded, so the recorded age was in error; Lu Bi and Mou Guangsheng argued instead that Cao Rui was Yuan Xi's son. Cao Rui's reign was viewed in many different ways throughout Chinese history. He devoted many resources into building palaces and ancestral temples, and his reign saw the stalemate between his empire, Shu Han, and Eastern Wu become more entrenched. His building projects and his desire to have many concubines (who numbered in the thousands) greatly exhausted the imperial treasury. On his deathbed, he has no biolo ...

Zhang Heng
Zhang Heng (; AD 78–139), formerly romanized as Chang Heng, was a Chinese polymathic scientist and statesman who lived during the Han dynasty. Educated in the capital cities of Luoyang and Chang'an, he achieved success as an astronomer, mathematician, seismologist, hydraulic engineer, inventor, geographer, cartographer, ethnographer, artist, poet, philosopher, politician, and literary scholar. Zhang Heng began his career as a minor civil servant in Nanyang. Eventually, he became Chief Astronomer, Prefect of the Majors for Official Carriages, and then Palace Attendant at the imperial court. His uncompromising stance on historical and calendrical issues led to his becoming a controversial figure, preventing him from rising to the status of Grand Historian. His political rivalry with the palace eunuchs during the reign of Emperor Shun (r. 125–144) led to his decision to retire from the central court to serve as an administrator of Hejian Kingdom in present-day Hebei.

Ma Jun (mechanical Engineer)
Ma Jun ( 220–265), courtesy name Deheng, was a Chinese mechanical engineer, inventor, and politician who lived in the state of Cao Wei during the Three Kingdoms period of China. His most notable invention was that of the south-pointing chariot, a directional compass vehicle which actually had no magnetic function, but was operated by use of differential gears (which applies equal amount of torque to driving wheels rotating at different speeds). It is because of this revolutionary device (and other achievements) that Ma Jun is known as one of the most brilliant mechanical engineers and inventors of his day (alongside Zhang Heng of the earlier Eastern Han dynasty). The device was re-invented by many after Ma Jun, including the astronomer and mathematician Zu Chongzhi (429–500). In the later medieval dynastic periods, Ma Jun's south-pointing chariot was combined in a single device with the distance-measuring odometer.
