Anh gãi lưng tôi, tôi gãi lưng anh

You Scratch My Back...

 

 Cách ngôn Mỹ nói ,"Anh gãi lưng tôi, tôi gãi lưng anh" chủ ý giúp qua giúp lại.

 

There is an old expression that says, "You scratch my back and I'll scratch yours" meaning, "You do a favor for me and I'll do a favor for you."

This is the first time I have seen this illustrated.
