Beginners in calligraphy, what is a post and a tablet?

Copybook for calligraphy is a sample of writing and copying. There are two kinds of stickers, one is stone rubbings and the other is ink. The former is also called stele study, and the latter is also called post-study. Stone tablet, commonly known as "Hei Hu" in the past, is not only a work of art with cultural and historical connotation, but also a combination of artistic taste and technological processing. In order to record the important events and grand celebrations of the former dynasty, the predecessors carved literary forms and calligraphers' handwriting on cliffs and stone tablets by famous craftsmen, so the stone tablets had multiple artistic contents and were also inlaid into axes or volumes, thus becoming a stone tablet (bēi tiè). Monument is a combination of monument and monument. In fact, "monument" refers to the rubbings of stone carvings, and "monument" refers to the ancient famous ink collected on wooden boards and stones.
