This proverb means that if we retaliate against someone who has wronged us, we will only cause more violence and conflict. It is better to forgive and forget, or to seek justice through the proper channels, than to take matters into our own hands.
The proverb is often used to勸告人们不要以暴制暴。以眼还眼、以牙还牙只会带来更多的暴力和冲突。宽恕和遗忘,或通过正当的渠道寻求正义,是更好的选择。
