You can hear what people say, but you don't have to take it to heart.

Everyone in this world has their own perspective. Some will admire you, and others will dislike you. Some criticisms have reasons, and some prejudices have no answers. People have their own beliefs, and you can't expect everyone to understand you with goodwill. When facing criticism and judgment, first reflect on yourself, don't rush to get angry; first discern right from wrong, don't rush to defend. If you've done wrong, correct it; if you haven't, don't be bothered by it. The most tiring thing for a person is not what others say about you, but taking every word to heart and tormenting yourself over it. No matter how perfect you are, you can't avoid others' prejudices; no matter how cautious you are, you can't shut the mouths of those who love to gossip. Maintain the etiquette you should, and uphold the virtues you should have. You don't need to explain yourself to everyone, nor prove yourself everywhere. You can hear what people say, but you don't have to take it to heart. Don't get lost in praise, don't be shaken by slander; Guard your own heart, and walk your own path. Life is finite, so don't waste your precious energy and heart on gossip and disputes.
