Add/Submit an Idiom

If you are a native Taiwanese person (Táiwān rén/台灣人) or a foreigner (lǎowái/老外) living in Taiwan (Táiwān/台灣) please submit your Mandarin Chinese Idiom that is Used In Taiwan below by adding it as a COMMENT along with the story/history/background/explanation of why it is an idiom (what it means). I will then add it to the front page (BLOG) so people can comment on that specific (certain) idiom.
