微笑不代表我快乐哭泣不代表我难过
[wēi xiào bù dài biăo wŏ kuài lè kū qì bù dài biăo wŏ nán guò]
It expresses complex emotions: 'a smile does not necessarily mean I am happy, and crying does not necessarily mean I am sad.' This signifies one’s inner feelings may not match their outward appearance or emotional display.
