What do you mean by blowing pillow wind?

Usually it means that a wife chats with her husband at night and expresses her opinion on a certain topic. This is called "blowing pillow breeze". Especially commonly used, someone wants a man, but can't ask for help directly (for example, the man pushes the request, or doesn't listen to the requester). At this time, he can only turn to the man's wife first, and let her blow a pillow breeze to her husband and say a good word to save the country. Finally, the wind around the pillow worked and the man agreed to help.
