1 If you want to learn hard-pen calligraphy, you might as well find some famous calligraphers such as Wang Xizhi, Wang Xianzhi, Huai Su monk, Zhu Suiliang, etc. to practice using pens and learn to write their bones, muscles and rules. The effect is good.
Many calligraphers' works have their own uniqueness, and there is no most beautiful statement, which depends on people. I prefer the words of Wang Xizhi and Tang Gaozong. In addition, the calligraphy of any school in the Song Dynasty is also good. (personal opinion)
