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").
Chinese calligraphy
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.
