If you want to write good brush calligraphy, you need to do plenty of model-copying practice.
Tips
culture
临帖 is the standard apprenticeship method in Chinese calligraphy. Students copy classic 字帖 (zìtiè, model books) such as 王羲之 (Wáng Xīzhī)'s 兰亭序 (Lántíng Xù) or 颜真卿 (Yán Zhēnqīng)'s works to absorb structure and stroke style.
usage
Note 帖 here is read tiè (4th tone), referring to a model copy book. The same character is read tiē (1st tone) in 服帖 (obedient) and tiě (3rd tone) in 请帖 (invitation card).
