The sentence "Don't look down on anyone" can correspond to Chapter 8 "The best is like water" in the Tao Te Ching. One of the sentences is "A person who is good at being a soldier does not use force; a person who is good at fighting does not get angry; a person who is good at defeating the enemy does not fight with him; a person who is good at using others does not fight." This means that a truly kind person does not fight. , does not get angry easily, does not fight with others, and is more modest and respectful to others. This is similar to the meaning of "Don't look down on anyone". They both express an attitude of respect and humility, reminding people not to be arrogant and to treat everyone around them with a peaceful attitude.
