Yang Xi
Although no autograph copies of Yang Xi's famous calligraphy have survived, one well-documented stone rubbing version of the revealed "Huangting jing" (黃庭經, Yellow Court Scripture) has been given special attention. The Song dynasty connoisseur and critic Mi Fu (1051-1107) analyzed four manuscripts of the "Huangting jing", and said the best one was written on a silk scroll with a provenance that he traced back to the early 8th century. Mi disagreed with a former owner Tao Gu (陶穀, 903-970) who said that Wang Xizhi wrote the manuscript, and concluded it was a superb example of calligraphy from the Six Dynasties period. The Ming dynasty calligrapher and painter Dong Qichang (1555-1636) was so impressed by the Mi Fu manuscript that he made a copy, recommend it as the best model for studying "kaishu" script, and included it as the first example in his classic "Xihong tang fatie" (戲鴻堂法帖, Calligraphy Compendium of the Hall of the Playful Goose). Dong's colophon attributed the calligraphy to Yang Xi himself and described it as "the traces of a holy immortal" (Ledderose 1984: 262-263, who calls Dong's attribution to Yang "extremely optimistic").
Calligraphy
In ancient China, the oldest Chinese characters existing are Jiǎgǔwén characters (甲骨文) carved on ox scapulae and tortoise plastrons, because the dominators in Shang Dynasty carved pits on such animals' bones and then baked them to gain auspice of military affairs, agricultural harvest, or even procreating and weather. During the divination ceremony, after the cracks were made, the characters were written with a brush on the shell or bone to be later carved. (Keightley, 1978). With the development of "Jīnwén" (Bronzeware script) and "Dàzhuàn" (Large Seal Script) "cursive" signs continued. Mao Gong Ding is one of the most famous and typical Bronzeware scripts in the Chinese calligraphy history. It has 500 characters on the bronze which is the largest number of bronze inscription we have discovered so far. . Moreover, each archaic kingdom of current China had its own set of characters.
