A copybook (Chinese: 字帖; pinyin: zìtiè) is a book containing examples of calligraphic script, meant to be copied while practicing calligraphy.
Later, people made rubbings of the stone on paper so that they could copy and learn the famous calligraphy.
Today children in China who enter school would have a copybook for learning characters.
Copybooks can help children practice different font of handwriting and build their own style.
[2] Since the Yin dynasty, it became popular to engrave words on stone to make them spread further and longer, but not calligraphy.
