Dong Yuhui gave a speech on CCTV: "How far a person can go has nothing to do with intelligence. It mainly depends on concentration." The world is changing rapidly, and only by maintaining concentration can we break through the situation and move forward. You can afford good things, you can withstand adversity, you can keep your emotions stable, and you can keep your mind. Things in the world are complicated, so you should have a detached attitude; you should handle the ups and downs of life calmly.
