The second step is to practice every stroke of Chinese characters: Chinese characters have a history of 5000 years, and our current Chinese characters are all square and composed of one stroke and one painting. To write a good hand, you must practice every stroke.
Finally, practice copybooks: I personally recommend describing regular script, and you can use copybooks from Liu Gongquan or Yan Zhenqing. Writing is ugly, don't practice running script or cursive script.
