What should I write in hard pen calligraphy? Don't write poetry, it's better to write articles of 100 to 200 words, both prose and ancient prose.

Ancient prose collection: random feelings, night talk around the stove.

Prose: The Wind Catcher by San Mao, Liu Yong and Mai Jia, Amazing and Beautiful by Tie Ning.

Essay: Bacon, Montaigne

I think it's not bad, elegant without losing depth, aesthetic feeling and philosophy coexist.
