人不犯我我不犯人人若犯我我必犯人
[rén bù fàn wŏ wŏ bù fàn rén rén ruò fàn wŏ wŏ bì fàn rén]
'If others don't offend me, I will not offend anyone; if they do wrong me, then I will act against them.' A Chinese idiomatic saying meaning to avoid conflict whenever possible, however retaliate when provoked. Reflects a belief in justice but also self-preservation.
