笑你如狗哭你如猫
[xiào nĭ rú gŏu kū nĭ rú māo]
'Xiao Ni Ru Gou Ku Ni Ru Mao' roughly translates into 'You laugh like a dog and cry like a cat'. This idiom portrays two distinctive behaviors of laughter and crying, one loud and frank, the other silent and mournful, perhaps pointing to different personas under different circumstances of the same person.
