Why is the word "senpai" widely misunderstood? http://tocana.jp/2015/12/post_8270_entry.html
The words "senpai" and "kouhai" are deeply rooted in 儒教 (Confucianism), a cultural system ruling in the east Asian countries. But foreign people seem to use these words without knowing Confucian philosophy and how much it controls our way of life.
