If you haven't started yet, you can find some videos to see the brushwork, recommend Mr. Tian's "One Word a Day" or "Analysis" (with the same name as Tian's book, but not Tian's explanation), and write modern European ink and wash for a while after you understand it (such as Wang Weixian, Chen Yishun, contemporary Wang Tiru, Tian, Brother, etc.). ), and then I started working in Ou Yangxun for nine years and made some achievements.
Other steles you can try without entering Jiucheng Palace, such as Huangfushengchen stele, Huadu Temple stele and Gongbei stele.
Pay attention to temporary posts, but attack word by word and write word by word until you are satisfied. At first, you may write the same word every day, or even write the same word for several days. With progress, we can learn more every day, and by learning word by word, we can make a layout of the rules and regulations.
