Li Chunfeng
Li Chunfeng (; 602–670) was a Chinese mathematician, astronomer, historian, and politician who was born in today's Baoji, Shaanxi, during the Sui and Tang dynasties. He was first appointed to the Imperial Astronomy Bureau to help institute a calendar reform. He eventually ascended to deputy of the Imperial Astronomy Bureau and designed the Linde calendar. His father was an educated state official and also a Taoist. Li died in Chang'an in 670. Background and career The Sui dynasty was integral for uniting China, so it was a good time for learning. But when Li was sixteen the Sui fell, and the Tang rose. Nevertheless, the Tang did not harm the conditions for education. Indeed, it rather strengthened it. The Imperial Academy's math teaching was formalized. He was appointed into the Imperial Astronomy Bureau as an advanced court astronomer and historian, in 627. Once several years had passed, he then was promoted to deputy director of the Imperial Astronomy Bureau in 641, and even d ...

Book Of Jin
The ''Book of Jin'' is an official Chinese historical text covering the history of the Jin dynasty from 266 to 420. It was compiled in 648 by a number of officials commissioned by the imperial court of the Tang dynasty, with chancellor Fang Xuanling as the lead editor, drawing mostly from official documents left from earlier archives. A few essays in volumes 1, 3, 54 and 80 were composed by the Tang dynasty's Emperor Taizong himself. However, the contents of the ''Book of Jin'' included not only the history of the Jin dynasty, but also that of the Sixteen Kingdoms period, which was contemporaneous with the Eastern Jin dynasty. Compilation Over 20 histories of the Jin had been written during the Northern and Southern dynasties, of which 18 were still extant at the beginning of the Tang dynasty. Yet Emperor Taizong deemed them all to be deficient and ordered the compilation of a new standard history for the period,Fang, Xuanling ''ed.''(2002). ''Jinshu'' 晋书. Beijing: Zhong ...

602 Births
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler". Six is a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinese Culture
Chinese culture () is one of the world's oldest cultures, originating thousands of years ago. The culture prevails across a large geographical region in East Asia and is extremely diverse and varying, with customs and traditions varying greatly between Province (China), provinces, Cities of China, cities, and even towns as well. The terms 'China' and the geographical landmass of 'China' have shifted across the centuries, with the last name being the Qing dynasty, Great Qing before the name 'China' became commonplace in modernity. Chinese civilization is historically considered a dominant culture of East Asia. With China being one of the Cradle of civilization#Ancient China, earliest ancient civilizations, Chinese culture exerts profound influence on the philosophy, virtue, etiquette, and traditions of Asia.

Ganying
''Gǎnyìng'' or ''yìng'' is a Chinese cultural keyword meaning a "correlative resonance" pulsating throughout the purported force field of '' qi'' that infuses the cosmos. When the idea of ''ganying'' first appeared in Chinese classics from the late Warring States period (475-221 BCE), it referred to a cosmological principle of "stimulus and response" between things of the same kind, analogous with vibratory sympathetic resonance. Early schools of Chinese philosophy adapted ''ganying'' into different folk theories of causality, such as universal resonance influencing all interrelated things in Daoism, and ethical resonance between Heaven and humans in Confucianism. ''Ganying'' resonance was later used to mean miraculous "moral retribution" in Chinese folk religion, and "prayers being heard" in Chinese Buddhism. In the modern period, Chinese ''ganying'' "stimulus and response" was used to translate some Western scientific loanwords (such as ''diàncí gǎnyìng'' 電磁感應 " ...

Tui Bei Tu
''Tui bei tu'' () is a Chinese prophecy book from the 7th-century Tang dynasty. The book is known for predicting the future of China, and is written by Li Chunfeng and Yuan Tiangang (袁天罡), and has been compared to the works of famous western prophet Nostradamus.Miles, James A. R. 996(1996). Legacy of Tiananmen: China in Disarray. University of Michigan. Well known in Hong Kong, Macau and Taiwan, the book was previously banned in the People's Republic of China under the Communist party for superstition (one of the “Four Olds”), though it has since reappeared in street-side book stalls in the 1990s as a bestseller. Description The book is supposed to contain clues to China's future conveyed through a series of 60 surreal drawings, each accompanied by an equally obscure poem. The title means "Back-Pushing Sketch" and comes from the last illustration. Each poem is a prophecy, which describes a Chinese historical event that will occur in order. For example, the 36t ...

Twenty-Four Histories
The ''Twenty-Four Histories'' (), also known as the ''Orthodox Histories'' (), are the Chinese official dynastic histories covering from the earliest dynasty in 3000 BC to the Ming dynasty in the 17th century. The Han dynasty official Sima Qian established many of the conventions of the genre, but the form was not fixed until much later. Starting with the Tang dynasty, each dynasty established an official office to write the history of its predecessor using official court records, partly in order to establish its own link to the earliest times. As fixed and edited in the Qing dynasty, the whole set contains 3,213 volumes and about 40 million words. It is considered one of the most important sources on Chinese history and culture. The title "Twenty-Four Histories" dates from 1775, which was the 40th year in the reign of the Qianlong Emperor. This was when the last volume, the ''History of Ming'', was reworked and a complete set of the histories was produced. Collection Inherit ...

Music
Music is generally defined as the art of arranging sound to create some combination of form, harmony, melody, rhythm or otherwise expressive content. Exact definitions of music vary considerably around the world, though it is an aspect of all human societies, a cultural universal. While scholars agree that music is defined by a few specific elements, there is no consensus on their precise definitions. The creation of music is commonly divided into musical composition, musical improvisation, and musical performance, though the topic itself extends into academic disciplines, criticism, philosophy, and psychology. Music may be performed or improvised using a vast range of instruments, including the human voice. In some musical contexts, a performance or composition may be to some extent improvised. For instance, in Hindustani classical music, the performer plays spontaneously while following a partially defined structure and using characteristic motifs. In modal jazz ...
