Restriction

Four boards of different materials are combined to form the bondage of the world. The mirror represents the bondage brought by the ideal illusory world, the fluorescent green acrylic plate represents the bondage brought by subjective prejudice, the black board represents the bondage brought by the pressure in ordinary life, and the fluorescent pink sponge board represents the bondage brought by the glitz in the society. The light bar outside the board emphasizes the restraint.
