The intellectual elite who followed the National Government of the ROC in its withdrawal from China to Taiwan in 1949, started a new era of cultural transfer and tradition. Mr. Ding, a learned calligrapher and brilliant critic, was among them. Among the calligraphy produced in Taiwan since 1945, the year in which Taiwan reverted to Chinese sovereignty following the surrender of Japan at the end of World War Ⅱ, his unique Clerical Style is regarded as outstanding; it has been surpassed by no one. Ding therefore enjoys immense acclaim in the world of calligraphy and is revered by all calligraphy masters. The essay is based on Mr. Ding’s treatises and discusses the writing of his calligraphy, how he collected 128 works of calligraphy to refer to and the particular features of his Clerical Style of calligraphy, a learned and refined “scholar’s calligraphy.” He learned from the Han tablets, and the three tablets in the Confucian temple, particularly focusing on the Lichi Tablet and Shihchen Tablet; he was deeply influenced by the inscription on the base and side of the Lichi Tablet; he was deeply influenced by the inscription on the base and side of the Lichi Tablet and from it developed the calligraphic regularities of closed spaces between words and lines. Whenever he imitated tablets, he adopted his own clerical style, which can be seen most clearly from the great titles to the works that he didn’t take particularly seriously. In addition, his clerical style combining with script style of calligraphy lends his work the rigid and graceful beauty which is one of its hallmarks.
