看透了你的真面目
        
            [kàn tòu le nĭ de zhēn miàn mù]
        
        
            Expresses that one has seen through someone's true nature, indicating disillusionment, possibly after initial appearances proved to be misleading or disappointing. A more literal translation would be 'seeing your true face clearly'—an act of realization after having experienced something or someone.
