出 林 笋子 先 打断
The bamboo shoots which grow outside the edge of the grove will be the first to be broken off.
This is a warning proverb – if you stick your neck out, you will be the first to be attacked! Very Chinese attitude really – stay with the majority view, don’t act or speak as a single individual; and I think it is true for Koreans and Japanese as well.
So presumably you should ‘keep your head below the parapet’ as we would say.
