What are the characteristics of Zhu Da's calligraphy?

Zhu Da's freehand flower-and-bird painting has created a new style with its unique function. His calligraphy is similar to his painting style, and it is extremely concise. In his later years, he likes to use bald pen, and his sharp brushwork is transformed into a round and simple style.

Zhu Da's five-character poem fan creates an artistic atmosphere with simple strokes and sparse rules, and its style is extraordinary and unconventional. The inscriptions on many paintings of Badashan people are quite wonderful and ingenious. If the layout of the painting is flawed, sometimes a book cloud is used to fill in its meaning. Badashan people can also write poems, so even if he doesn't draw much, he can write his own poems at will, and the artistic conception is enough.
