In regular script, you can choose Yan Qinli Monument in Yan style, which is characterized by thin horizontal lines and thick vertical lines, with obvious contrast
The characters of Su Shi in thick cursive script are very thick, but I feel that only those who are good at calligraphy can Only talents can appreciate it. A layman can't tell what is good. I recommend Mi Fu's running script, which has personality. Wang Xizhi's running script is elegant, like flowing clouds and flowing water, and is highly appreciative
The official script of Zhang Qian's stele is thick and thick, but I feel that ordinary people can’t appreciate it. I feel that the Yiying Monument also meets your requirements, but I personally feel that the official script is not very suitable. However, if you want to get the official script, I recommend the official script of Jin Nong in the Qing Dynasty. I personally feel that Jin Nong’s official script is good and unique
Small seal script is generally used in seal script, which is very pretentious, but people who don’t practice calligraphy nowadays generally don’t know small seal script. I only know a little about small seal script, and I feel that most people don’t care too much
As for large seal scripts and oracle bone inscriptions, most people see them as irregular strokes
So to sum up, I personally recommend Yan Zhenqing’s Yan Qin Li Stele, Mi Fu Shu Su Tie or Tiao Xi Poetry Post, Wang Xizhi’s Lanting Preface or The Preface to the Holy Religion of Collection of Characters, Yiying Stele, and Jinnong Official Script. You can search the images on Baidu to see which one you like better.
