假朋友是喂不熟的狗真朋友是甩不掉的虫
[jiă péng yŏu shì wèi bù shú de gŏu zhēn péng yŏu shì shuăi bù diào de chóng]
'Fake friends are dogs that can never be tamed, real friends are bugs you can't shake off'. This nickname describes two opposite situations about friendships. One has shallow relationships while another clings all the time, which implies a kind of helplessness about friendship.
