Chinese calligraphy is a type of pleasing writing, as well as a kind of sport, embodying the artistic expression of human language in a tangible form. This type of expression has been widely practiced in China and has been generally held in high esteem across East Asia. Calligraphy is considered as one of the four best friends of ancient Chinese literati, along with playing stringed musical instrument, the board game "Go", and painting. There are some general standardizations of the various styles of calligraphy in this tradition. Chinese calligraphy and ink and wash painting are closely related: they are accomplished using similar tools and techniques, and have a long history of shared artistry. Distinguishing features of Chinese painting and calligraphy include an emphasis on motion charged with dynamic life. According to Stanley-Baker, "Calligraphy is sheer life experienced through energy in motion that is registered as traces on silk or paper, with time and rhythm in shifting space its main ingredients." Calligraphy has also led to the development of many forms of art in China, including seal carving, ornate paperweights, and inkstones.
In China, calligraphy is referred to as shūfǎ (書法/书法), literally 'way/method/law of writing'; shodō (書道) in Japan ('way/principle of writing'); and seoye (서예; 書藝) in Korea ('skill/criterion of writing').
Chinese calligraphy appreciated more or only for its aesthetic quality has a long tradition, and is today regarded as one of the arts (Chinese 藝術/艺术 pinyin: yìshù, a relatively recent word in Chinese) in the countries where it is practised. Chinese calligraphy focuses not only on methods of writing but also on cultivating one's character (人品) and taught as a pursuit (－書法; pinyin: shūfǎ, rules of writing Han characters).
Oracle bone script was one of the forms of Chinese character written on animals bones. Written on oracle bones – animal bones or turtle plastrons, it is the earliest known form of Chinese writing. The first appearance of what we recognize unequivocally to refer as “oracle bone inscriptions” comes in the form of inscribed ox scapula and turtle plastrons from sites near modern Anyang (安阳) on the northern border of Henan province. The vast majority were found at the Yinxu site (in modern Anyang, Henan Province). They record pyromantic divinations of the last nine kings of the Shang dynasty, beginning with Wu Ding, whose accession is dated by different scholars at 1250 BC or 1200 BC. Even though there is no proof that the Shang dynasty were solely responsible for the origin of writing in China, but neither is there evidence of recognizable Chinese writing from any earlier time or any other place. The late Shang oracle bone writings constitute the earliest significant corpus of Chinese writing and it is also the oldest known member and ancestor of the Chinese family of scripts, preceding the Chinese bronze inscriptions.
Chinese bronze inscriptions are a kind of style that usually written on the Chinese ritual bronzes. These Chinese ritual bronzes include Ding (鼎), Dui (敦), Gu (觚), Guang (觥), Gui (簋), Hu (壺), Jia (斝), Jue (爵), Yi (匜), You (卣), Zun (尊), and Yi (彝). Different time period has different method of inscription. Shang bronze inscriptions were nearly all cast along with the implements on which they appear. In later dynasty such as Western Zhou, Spring and Autumn Period, the inscriptions were often engraved after the bronze was cast. The bronze inscriptions are one of the earliest scripts in the Chinese family of scripts, preceded by the oracle bone script.
Seal script (Chinese: 篆書; pinyin: zhuànshū) is an ancient style of writing Chinese characters that was common throughout the latter half of the 1st millennium BC. It evolved organically out of the Zhou dynasty script. The Qin variant of seal script eventually became the standard, and was adopted as the formal script for all of China during the Qin dynasty.
The Clerical script (traditional Chinese: 隸書; simplified Chinese: 隶书; pinyin: lìshū) is an archaic style of Chinese calligraphy. The clerical script began during Han dynasty and has lasted up to the present. The clerical script is considered as a form of modern script even though it was replaced by the standard script by very early date. It was all because the graphic forms written in mature clerical script closely resemble those written in standard script. The clerical script is still used for artistic flavor in a variety of functional applications because of its high legibility of reading.
Regular script (traditional Chinese: 楷書; simplified Chinese: 楷书; pinyin: ) is the newest of the Chinese script styles. The regular script first come into existence between the Han and Wei dynasties, even though it is not popular. The regular script becomes mature stylistically around the 7th century. The first master of regular script is Zhong You. Zhong You first used regular script to write some very serious pieces such as memorials to the emperor.kǎishū; Hong Kong and Taiwan still use traditional Chinese characters in writing, while mainland China uses simplified Chinese characters to be the official script.
Semi-cursive script also known as (simplified Chinese: 行书; traditional Chinese: 行書; pinyin: Xíng), is a cursive style of Chinese characters. Because it is not as abbreviated as cursive, most people who can read regular script can read semi-cursive. It is highly useful and also artistic.
Cursive script, also known as (simplified Chinese: 草书; traditional Chinese: 草書; pinyin: cǎoshū), originated in China during the Han dynasty through the Jin period (link needed). The cursive script is faster to write than other styles, but difficult to read for those unfamiliar with it. The “grass” in Chinese was also used in the sense of “coarse, rough; simple and crude.” It would appear that cǎo in the term caoshu “grass script” was used in this same sense. The term cǎoshū has broad and narrow meanings. In the broad sense, it is non-temporal and can refer to any characters which have been hastily written. In the narrow sense, it refers to the specific handwriting style in Han dynasty.
Chinese characters can be retraced to 4000 B.C.E signs (Lu & Aiken 2004).
In 2003, at the site of Xiaoshuangqiao (小双桥), about 20 km southeast of the ancient Zhengzhou Shang City, ceramic inscriptions dating to 1435–1412 B.C.E have been found by archaeologists. These writings are made in cinnabar paint. Thus, the dates of writing in China have been confirmed for the Middle Shang period.
The ceramic ritual vessel vats that bear these cinnabar inscriptions were all unearthed within the palace area of this site. They were unearthed mostly in the sacrificial pits holding cow skulls and cow horns, but also in other architectural areas. The inscriptions are written on the exterior and interior of the rim, and the exterior of the belly of the large type of vats. The characters are mostly written singly; character compounds or sentences are rarely seen.
The contemporary Chinese character's set principles were clearly visible in ancient China's Jiǎgǔwén characters(甲骨文) carved on ox scapulas and tortoise plastrons around 14th - 11th century BCE (Lu & Aiken 2004). Brush-written examples decay over time and have not survived. During the divination ceremony, after the cracks were made, characters were written with a brush on the shell or bone to be later carved (Keightley, 1978). Each archaic kingdom of current China continued to revise its set of characters.
For more than 2,000 years, China's literati—Confucian scholars and literary men who also served the government as officials—have been connoisseurs and practitioners of this art. In Imperial China, the graphs on old steles — some dating from 200 BC, and in Xiǎozhuàn style (small seal script) — are still accessible.
In about 220 BC, the emperor Qin Shi Huang（秦始皇, 259–210 BCE）, the first to conquer the entire Chinese basin, imposed several reforms, among them Li Si's (李斯, 246 BCE - 208 BCE) character unification, which created a set of 3300 standardized Xiǎozhuàn characters. Despite the fact that the main writing implement of the time was already the brush, little paper survives from this period, and the main examples of this style are on steles.
The Lìshū style (clerical script) which is more regularized, and in some ways similar to modern text, were also authorised under Qin Shi Huang. While it is a common mistake to believe that Lishu was created by Cheng Miao alone during Qing Shi Huang’ regime, Lishu was developed from pre-Qin era to the Han dynasty (202 BCE-220 CE).
During the fourth century CE, calligraphy came to full maturity. The Kǎishū style (traditional regular script) — still in use today — and attributed to Wang Xizhi (王羲之, 303 CE-361 CE) and his followers, is even more regularized. reached its peak in the Tang Dynasty, when famous calligraphers like Yan Zhenqing and Liu Gongquan produced most of the fine works in Kaishu. Its spread was encouraged by Emperor Mingzong of Later Tang (926 CE -933 CE), who ordered the printing of the classics using new wooden blocks in Kaishu. Printing technologies here allowed shapes to stabilize. The Kaishu shape of characters 1000 years ago was mostly similar to that at the end of Imperial China. But small changes have been made, for example in the shape of 广 which is not absolutely the same in the Kangxi Dictionary of 1716 as in modern books. The Kangxi and current shapes have tiny differences, while stroke order is still the same, according to old style.
Cursive styles such as Xíngshū (semi-cursive or running script) and Cǎoshū (cursive or sloppy script) are less constrained and faster, where more movements made by the writing implement are visible. These styles' stroke orders vary more, sometimes creating radically different forms. They are descended from Clerical script, at the same time as Regular script (Han Dynasty 202 BCE-220 CE), but Xíngshū and Cǎoshū were used for personal notes only and were never used as a standard. Caoshu style was highly appreciated during the reign of Emperor Wu of Han (140 BCE−87 BCE).
Styles which did not survive include Bāfēnshū, a mix of 80% Xiaozhuan style and 20% Lishu. Some Variant Chinese characters were unorthodox or locally used for centuries. They were generally understood but always rejected in official texts. Some of these unorthodox variants, in addition to some newly created characters, were incorporated in the Simplified Chinese character set.
This way of writing started to develop in the 1900s when fountain pens were imported into China from the west. Writing with fountain pens remained a convenience until the 1980s. With the Reform and Open, public focused on practicing hard-pen calligraphy. People usually use Chinese simplified characters in semi-cursive or regular style.
The ink brush, ink, paper, and inkstone are essential implements of Chinese calligraphy. They are known together as the Four Treasures of the Study. In addition to these four tools, a water-dropper, desk pads and paperweights are also used by calligraphers.
A brush is the traditional writing instrument for Chinese calligraphy. The body of the brush is commonly made from bamboo or other materials such as wood, porcelain, or horn. The head of the brush is typically made from animal hair, such as weasel, rabbit, deer, goat, pig, tiger, wolf, etc. There is also a tradition in both China and Japan of making a brush using the hair of a newborn child, as a once-in-a-lifetime souvenir. This practice is associated with the legend of an ancient Chinese scholar who scored first in the imperial examinations by using such a personalized brush. Calligraphy brushes are widely considered an extension of the calligrapher's arm.
Some people insist that Chinese calligraphy should use special papers, such as Xuan paper, Maobian paper, Lianshi paper etc. Any modern papers can be used for brush writing. Because of the long-term uses, Xuan paper became well known by most of Chinese calligraphers.
In China, Xuanzhi (宣紙), traditionally made in Anhui province, is the preferred type of paper. It is made from the Tatar wingceltis (Pteroceltis tatarianovii), as well as other materials including rice, the paper mulberry (Broussonetia papyrifera), bamboo, hemp, etc. In Japan, washi is made from the kozo (paper mulberry), ganpi (Wikstroemia sikokiana), and mitsumata (Edgeworthia papyrifera), as well as other materials such as bamboo, rice, and wheat.
Paperweights are used to hold down paper. A paperweight is often placed at the top of all but the largest pages to prevent slipping; for smaller pieces the left hand is also placed at the bottom of the page for support. Paperweights come in several types: some are oblong wooden blocks carved with calligraphic or pictorial designs; others are essentially small sculptures of people or animals. Like ink stones, paperweights are collectible works of art on their own right.
The desk pad (Chinese T: 畫氈, S: 画毡, Pinyin: huàzhān; Japanese: 下敷 shitajiki) is a pad made of felt. Some are printed with grids on both sides, so that when it is placed under the translucent paper, it can be used as a guide to ensure correct placement and size of characters. However, these printed pads are used only by students. Both desk pads and the printed grids come in a variety of sizes.
Ink is made from lampblack (soot) and binders, and comes in inksticks which must be rubbed with water on an inkstone until the right consistency is achieved. Much cheaper, pre-mixed bottled inks are now available, but these are used primarily for practice as stick inks are considered higher quality and chemical inks are more prone to bleeding over time, making them less suitable for use in hanging scrolls. Learning to rub the ink is an essential part of calligraphy study. Traditionally, Chinese calligraphy is written only in black ink, but modern calligraphers sometimes use other colors. Calligraphy teachers use a bright orange or red ink with which they write practice characters on which students trace, or to correct students' work.
Commonly made from stone, ceramic, or clay, an inkstone is used to grind the solid inkstick into liquid ink and to contain the ink once it is liquid. Chinese inkstones are highly prized as art objects and an extensive bibliography is dedicated to their history and appreciation, especially in China.
Calligraphic works are usually completed by the calligrapher applying one or more seals in red ink. The seal can serve the function of a signature.
The shape, size, stretch, and type of hair in the brush, the color and density of the ink, as well as the absorptive speed and surface texture of the paper are the main physical parameters influencing the final result. The calligrapher also influences the result by the quantity of ink/water he lets the brush take up, then by the pressure, inclination, and direction he gives to the brush, producing thinner or bolder strokes, and smooth or toothed borders. Eventually, the speed, acceleration and deceleration of the writer's moves and turns, and the stroke order give "spirit" to the characters by influencing greatly their final shape. The “spirit” is referred to yi in Chinese calligraphy. Yi means “intention or idea” in Chinese. The more practice a calligrapher has, his or her technique will transfer from youyi (intentionally making a piece of work) to wuyi (creating art with unintentional moves). Wuyi is considered as a higher stage for calligraphers, which require the calligrapher to have perfect control over the brush and wrist and following his or her heart.
Traditionally, the bulk of the study of calligraphy is composed of copying strictly exemplary works from the apprentice's master or from reputed calligraphers, thus learning them by rote. The master showing the 'right way' to draw items, which the apprentice have to copy strictly, continuously, until the move becomes instinctive and the copy perfect. Deviation from the model is seen as a failure. Competency in a particular style often requires many years of practice. Correct strokes, stroke order, character structure, balance, and rhythm are essential in calligraphy. A student would also develop their skills in traditional Chinese arts, as familiarity and ability in the arts contributes to their calligraphy.
Since the development of regular script, nearly all calligraphers have started their study by imitating exemplary models of regular script. A beginning student may practice writing the character 永 (Chinese: yǒng, eternal) for its abundance of different kinds of strokes and difficulty in construction. The Eight Principles of Yong refers to the eight different strokes in the character, which some argue summarizes the different strokes in regular script.
How the brush is held depends on the calligrapher and which calligraphic genre is practiced. Commonly, the brush is held vertically straight gripped between the thumb and middle finger. The index finger lightly touches the upper part of the shaft of the brush (stabilizing it) while the ring and little fingers tuck under the bottom of the shaft, leaving a space inside the palm. Alternatively, the brush is held in the right hand between the thumb and the index finger, very much like a Western pen. A calligrapher may change his or her grip depending on the style and script. For example, a calligrapher may grip higher for cursive and lower for regular script.
In Japan, smaller pieces of Japanese calligraphy are traditionally written while in seiza. In modern times, however, writers frequently practice calligraphy seated on a chair at a table. Larger pieces may be written while standing; in this case the paper is usually placed directly on the floor, but some calligraphers use an easel.
Basic calligraphy instruction is part of the regular school curriculum in both China and Japan and specialized programs of study exist at the higher education level in China, Japan, Korea, and Taiwan. In contemporary times, debate emerged on the limits of this copyist tradition within the modern art scenes, where innovation is the rule, while changing lifestyles, tools, and colors are also influencing new waves of masters.
In recent study, Chinese calligraphy writing have been used as cognitive intervention strategy among older adults or people with mild cognitive impairment. For example, in a recent randomized control trial experiment, calligraphy writing enhanced both working memory and attention control compared to controlled groups 
While appreciating calligraphy will depend on individual preferences, there are established traditional rules and those who repeatedly violate them are not considered legitimate calligraphers. The famous modern Chinese calligrapher Tian Yunzhang, member of the Chinese Calligrapher Association, summarized rules of modern calligraphy. The following citation are from the video collection Mei ri yi ti mei ri yi zi (每日一题，每日一字) [zh] regarded as great reference for calligraphy learners, in which Tian made deep analysis of different characters. Among these rules are:
The Japanese and Koreans have developed their own specific sensibilities and styles of calligraphy while incorporating Chinese influences, as well as applying to specific scripts. Japanese calligraphy extends beyond Han characters to also include local scripts such as hiragana and katakana.
The existence of temporary calligraphy is also to be noted. This is the practice of water-only calligraphy on the floor which dries out within minutes. This practice is especially appreciated by the new generation of retired Chinese in public parks of China.
Calligraphy has influenced ink and wash painting, which is accomplished using similar tools and techniques. Calligraphy has influenced most major art styles in East Asia, including Ink and wash painting, a style of Chinese, Japanese, and Korean painting based entirely on calligraphy.
