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。”
孔子说：“君子有九种事情要考虑：看要考虑是否看清楚了、听要考虑是否听清楚了、脸色要考虑是否温和、表情要考虑是否谦恭、言谈时要考虑是否忠诚、工作时要考虑是否敬业、疑问时要考虑请教、愤怒时要考虑后患、见到好处时要考虑道义。”
故事就是光。在如此黑暗的世界里，光弥足珍贵。
The joy of discovery is what keeps me motivated after all these years.

Mathematics is not a spectator sport. You have to get involved.
The moment you recognize what is beautiful in this world, you stop being a slave.
