Historical Sequence of Yiying Monument in Cao Quanbei, Zhang Qianbei

As far as official script is concerned, the historical sequence is "Yi Ying Bei", "Zhang Qianbei" and "Cao Quanbei". "Ancient Calligraphy in China-Lishu" is a special stamp issued by People's Republic of China (PRC) and the State Post Bureau on February 5, 2004, numbered 2004-28. There are 4 stamps of China Ancient Calligraphy-Official Book, which depict the local characteristics of Yiying Monument, Zhang Qianbei, Cao Quanbei and Shimen Song rubbings respectively. The basic feature of Lishu is to change the embracing line frame of Lishu into a horizontal and vertical folding line frame. The shape of the official script changed from slender to flat, stacked tightly up and down, and opened left and right. Every word is exaggerated, which constitutes the unique features of official script, that is, the so-called silkworm head and goose tail, which makes the image of calligraphy both simple and implicit and high-spirited, greatly enriching the expressive function and lyrical function of China's calligraphy and expanding it. Judging from a large number of official script inscriptions, the world of official script in the Eastern Han Dynasty was mature and varied in style, among which Yi Yingbei, Zhang Qianbei, Cao Quanbei and Ode to Shimen were the four most influential masterpieces in history, representing the four main styles of official script.
