What is the sketch of Chinese painting?

Chinese painting sketches not only use things around them, but also use flowers, birds, fish and insects to express freehand brushwork life. Small-scale painting is a relatively free and lyrical work of China painters, which often reaches a higher artistic level. The reason is probably that there is not much restraint in thinking, which must be caused by random play.

In restaurants, hotels, guesthouses, most of them are small paintings hanging in the bathroom.
