灰太狼有个蓝颜叫光头强
[huī tài láng yŏu gè lán yán jiào guāng tóu qiáng]
'The Goofy Grey Wolf has a blue companion named Bald Strong' In the Chinese animated show Boonie Bears, the protagonist Guangtou Qiang (Strong the Bald) fights against deforestation. He is known for his wit, courage and perseverance. 'Gray Wolf(Huitaolang)' often fails but remains relentless; the word choice 'blue(blued face)' is a traditional way in Peking opera roles denoting loyalty and courage. So it is probably referring to two persons with completely different characteristics becoming companions or friends unexpectedly, expressing a humorous or surprising friendship.
