Marxism is a telescope through which we can clearly see the trends according to which reality develops, and a microscope through which we can see its crucial details. It is a set of night-vision goggles through which we can see light and hope in the darkness, a set of diving goggles through which we can see things at a deeper level, a fluoroscope through which we can see into the nature of the matter beyond the level of appearance, and a megaloscope through which we can make sense of blurred images. Marxism is a reflector through which we can see the truth behind things, a polygonal mirror that enables us to see the diversity and unity of opposites, an asymptotic mirror that allows us to see things near and far with multiple focal points and a monster-revealing mirror in which, if we have sharp eyes, we can see mistakes clearly. - Cheng Enfu
