Novices in calligraphy can practice regular script, official script or seal script first. Regular script: European style, Yan style, Liu style and Zhao Ti style. Official scripts: Zhang Qianbei, Cao Quanbei, Yi Yingbei, Shi Chenbei, etc. Seal script: Xiao seal script (Yishan tablet), Da seal script (Shisanpan), etc.
As for which tablet to choose, it is suggested that scholars go to the bookstore to look through these copybooks and practice that one if they like, because they will make faster progress because they like it.
