Is it useful to practice hard pen calligraphy reference (nine successes)?

I wonder how old you are. If you practice for a year, you should know some basic problems. You have raised a very important question of practicing hard pen calligraphy, that is, selecting posts, which shows that you are very clear about the basic path of practicing calligraphy. French posts are like flowers, so it's really hard to choose. I think we should grasp the following principles:

1, be sure to choose ancient posts. There is no reason here, there is no need for any argument, we must choose ancient posts.

2. Choose a position suitable for hard writing. Ancient calligraphy posts were all written with a brush, so many posts were not suitable for practicing hard pen. For example, Yan Zhenqing's "Duota" is basically suitable for practicing hard pen, while "Exquisite Monument" and "Ma Gu Xian Tan" are not suitable. The so-called suitable for practicing hard pen, generally speaking, is that the strokes are relatively thin and the thickness changes little. More suitable, but also many hard-pen calligraphers and enthusiasts choose more, such as Zhong You, Wang Xizhi, Wang Xianzhi's small letters, too many, go and see for yourself. Wei Bei's more delicate works are Zhang Heinv and Zhang Menglong. Ling Fei Jing, Jiucheng Palace, Huadu Temple, Preface to the Sacred Teaching of Chu Suiliang Yanta, Monument to the Temple of Confucius in the South of the Tang Dynasty, and Inscription on Brick Pagoda. Lower case letters of Zhao Mengfu and Wen Zhiming in Yuan and Ming Dynasties. Very many.

3. Choose what you like. Since there are so many calligraphy posts suitable for practicing hard pen, it is easy to be dazzled, which requires you to choose what you like and which is similar to your aesthetic tendency. You mentioned Jiucheng Palace, which is very good. Of course, you have to like it yourself. If you choose a good book, don't change your direction easily. Keep practicing for a year or two, and you will get something.
