Smart and eager to learn, and not ashamed to ask questions. ——"The Analects of Confucius·Gongye Chang"

The first sign of an educated mind is being good at asking questions. ——Plekhanov

A person who asks questions is only five kinds of fools; a person who is ashamed to ask questions will always be a fool. ——Anonymous

You can’t succeed if you don’t learn, and you don’t know if you don’t ask. ——Wang Chong of the Han Dynasty, "Lunheng·Practical Knowledge Chapter"

A gentleman must be good at asking questions, and asking and learning complement each other. Without learning, there is no doubt; without questioning, there is no broad knowledge.

——Liu Kai
