孔子曰，君子有九思，视思明，听思聪，色思温，貌思恭，言思忠，事思敬，疑思问，忿思难，见得思义。

James Legge Translation

Confucius said, "The superior man has nine things which are subjects with him of thoughtful consideration. In regard to the use of his eyes, he is anxious to see clearly. In regard to the use of his ears, he is anxious to hear distinctly. In regard to his countenance, he is anxious that it should be benign. In regard to his demeanor, he is anxious that it should be respectful. In regard to his speech, he is anxious that it should be sincere. In regard to his doing of business, he is anxious that it should be reverently careful. In regard to what he doubts about, he is anxious to question others. When he is angry, he thinks of the difficulties (his anger may involve him in). When he sees gain to be got, he thinks of righteousness."
