As a preliminary training method to solve the basic skills of art, mannequin sketch can be critically inherited. " "Sketching by real people (models) is an important method of basic art training.

In order to deeply study the movement, structure, proportion and form of the human body, there must be at least a certain proportion of human body exercises in oil paintings and sculptures. " "Since the abolition of the model system, teaching activities have encountered many difficulties, and the creative quality of recent graduates may be affected. It is suggested that in the fourth stage of the "four clean-ups", the masses should be mobilized for democratic discussion, and a new art education system should be established steadily and completely after repeated experiments.
