"A Workman Must First Sharpen His Tools"

From the back side of an AIDS brochure with very low production values from about five years ago.

I don't know about the other weird idioms, but the last one (The "C" Episode) is a Confucian proverb - "Before he embarks on a task, a workman must first sharpen his tools if he is to do his work well".

Good job, Executive Yuan AIDS Prevention Committee, for using a Confucian proverb in completely the wrong setting and in such a giggle-inducing way!

Enjoy!
