Chi (length)
The chi (Tongyong Pinyin chih) is a traditional Chinese unit of length. Although it is often translated as the "", its length was originally derived from the distance measured by a human hand, from the tip of the thumb to the tip of the forefinger, and is similar to the ancient span. It first appeared during China's Shang dynasty approximately 3,000 years ago and has since been adopted by other East Asian cultures such as Japan ('' shaku''), Korea (''ja/cheok''), and Vietnam (''thước''). Its present value is standardized at around , although the exact standards vary among the mainland of the People's Republic of China, its special administrative region of Hong Kong, and Taiwan. In its ancient and modern forms, the chi is divided into 10 smaller units known as cun (the "Chinese inch"). 10 chi are equal to 1 zhàng. Modern values In the People's Republic of China, ''chi'' has been defined since 1984 as exactly 1/3 of a metre, i.e., . However, in the Hong Kong SAR the c ...

Chinese Units Of Measurement
Chinese units of measurement, known in Chinese as the ''shìzhì'' ("market system"), are the traditional units of measurement of the Han Chinese. Although Chinese numerals have been decimal (base-10) since the Shang dynasty, Shang, several Chinese measures use hexadecimal (base-16). Local applications have varied, but the Chinese dynasties usually proclaimed standard measurements and recorded their predecessor's systems in Chinese dynastic histories, their histories. In the present day, the People's Republic of China maintains some customary units based upon the market units but standardized to round values in the metric system, for example the common ''jin'' or catty (unit), catty of exactly 500gram (unit), g. The Chinese name for most metric units is based on that of the closest traditional unit; when confusion might arise, the word "market" (, ''shì'') is used to specify the traditional unit and "common" or "public" (, ''gōng'') is used for the metric value. Taiwan, like Ko ...

Han Dynasty
The Han dynasty (, ; ) was an imperial dynasty of China (202 BC – 9 AD, 25–220 AD), established by Liu Bang (Emperor Gao) and ruled by the House of Liu. The dynasty was preceded by the short-lived Qin dynasty (221–207 BC) and a warring interregnum known as the ChuHan contention (206–202 BC), and it was succeeded by the Three Kingdoms period (220–280 AD). The dynasty was briefly interrupted by the Xin dynasty (9–23 AD) established by usurping regent Wang Mang, and is thus separated into two periods—the Western Han (202 BC – 9 AD) and the Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history, and it has influenced the identity of the Chinese civilization ever since. Modern China's majority ethnic group refers to themselves as the "Han people", the Sinitic language is known as "Han language", and the written Chinese is referred to as "Han characters". The emperor was at the pinnacle of ...

Qin Dynasty
The Qin dynasty ( ; zh, c=秦朝, p=Qín cháo, w=), or Ch'in dynasty in Wade–Giles romanization ( zh, c=, p=, w=Ch'in ch'ao), was the first Dynasties in Chinese history, dynasty of Imperial China. Named for its heartland in Qin (state), Qin state (modern Gansu and Shaanxi), the Qin dynasty arose as a fief of the Western Zhou and endured for over five centuries until 221 BCE when it founded its brief empire, which lasted only until 206 BCE. It often causes confusion that the ruling family of the Qin kingdom (what is conventionally called a "dynasty") ruled for over five centuries, while the "Qin Dynasty," the conventional name for the first Chinese empire, comprises the last fourteen years of Qin's existence. The divide between these two periods occurred in 221 BCE when King Zheng of Qin declared himself the Qin Shi Huang, First Emperor of Qin, though he had already been king of Qin since 246 BCE. Qin was a minor power for the early centuries of its existence. The streng ...

Rulers
A ruler, sometimes called a rule, line gauge, or scale, is a device used in geometry and technical drawing, as well as the engineering and construction industries, to measure distances or draw straight lines. Variants Rulers have long been made from different materials and in multiple sizes. Some are wooden. Plastics have also been used since they were invented; they can be molded with length markings instead of being scribed. Metal is used for more durable rulers for use in the workshop; sometimes a metal edge is embedded into a wooden desk ruler to preserve the edge when used for straight-line cutting. in length is useful for a ruler to be kept on a desk to help in drawing. Shorter rulers are convenient for keeping in a pocket. Longer rulers, e.g., , are necessary in some cases. Rigid wooden or plastic yardsticks, 1 yard long, and meter sticks, 1 meter long, are also used. Classically, long measuring rods were used for larger projects, now superseded by tap ...

Japanese Units Of Measurement
Traditional Japanese units of measurement or the shakkanhō (, "''shaku–kan'' system") is the traditional system of measurement used by the people of the Japanese archipelago. It is largely based on the Chinese system, which spread to Japan and the rest of the Sinosphere in antiquity. It has remained mostly unaltered since the adoption of the measures of the Tang dynasty in 701. Following the 1868 Meiji Restoration, Imperial Japan adopted the metric system and defined the traditional units in metric terms on the basis of a prototype metre and kilogram. The present values of most Korean and Taiwanese units of measurement derive from these values as well. For a time in the early 20th century, the traditional, metric, and English systems were all legal in Japan. Although commerce has since been legally restricted to using the metric system, the old system is still used in some instances. The old measures are common in carpentry and agriculture, with tools such as chisels, spatels ...

Cantonese Language
Cantonese ( zh, t=廣東話, s=广东话, first=t, cy=Gwóngdūng wá) is a language within the Chinese (Sinitic) branch of the Sino-Tibetan languages originating from the city of Guangzhou (historically known as Canton) and its surrounding area in Southeastern China. It is the traditional prestige variety of the Yue Chinese dialect group, which has over 80 million native speakers. While the term ''Cantonese'' specifically refers to the prestige variety, it is often used to refer to the entire Yue subgroup of Chinese, including related but largely mutually unintelligible languages and dialects such as Taishanese. Cantonese is viewed as a vital and inseparable part of the cultural identity for its native speakers across large swaths of Southeastern China, Hong Kong and Macau, as well as in overseas communities. In mainland China, it is the ''lingua franca'' of the province of Guangdong (being the majority language of the Pearl River Delta) and neighbouring areas such as Guangx ...

Shuowen Jiezi
''Shuowen Jiezi'' () is an ancient Chinese dictionary from the Han dynasty. Although not the first comprehensive Chinese character dictionary (the '' Erya'' predates it), it was the first to analyze the structure of the characters and to give the rationale behind them, as well as the first to use the principle of organization by sections with shared components called radicals (''bùshǒu'' 部首, lit. "section headers"). Circumstances of compilation Xu Shen, a Han Dynasty scholar of the Five Classics, compiled the ''Shuowen Jiezi''. He finished editing it in 100 CE, but due to an unfavorable imperial attitude towards scholarship, he waited until 121 CE before having his son Xǔ Chōng present it to Emperor An of Han along with a memorial. In analyzing the structure of characters and defining the words represented by them, Xu Shen strove to disambiguate the meaning of the pre-Han Classics, so as to render their usage by government unquestioned and bring about order, and in ...

Zhàng
The zhang ( zh, c= ) is a customary Chinese unit of length equal to 10 chi (Chinese feet). Its value varied over time and place with different values of the chi, although it was occasionally standardized. In 1915, the Republic of China set it equal to about 3.2meters or 3.50yards. In 1930, this was revised to an exact value of 3⅓meters (about 3.645yd). It is not commonly used in mainland China today but appears in traditional Chinese architecture, where it was commonly used to measure bays. In Japanese units of measurement, the is equivalent to ten ''shaku'', or 3.03 meters.

Cun (unit)
A ''cun'' (), often glossed as the ''Chinese inch'', is a traditional Chinese unit of length. Its traditional measure is the width of a person's thumb at the knuckle, whereas the width of the two forefingers denotes 1.5 cun and the width of four fingers (except the thumb) side-by-side is 3 cuns. It continues to be used to chart acupuncture points on the human body, and, in various uses for traditional Chinese medicine. The cun was part of a larger decimal system. A cun was made up of 10 fen, which depending on the period approximated lengths or widths of millet grains, and represented one-tenth of a chi ("Chinese foot"). In time the lengths were standardized, although to different values in different jurisdictions. (See chi (unit) for details.) In Hong Kong, using the traditional standard, it measures ~3.715 cm (~1.463 in) and is written "tsun". In the twentieth century in the Republic of China, the lengths were standardized to fit with the metric system, an ...
