"Worry about the world first, and enjoy the world later" comes from the Song Dynasty-Fan Zhongyan's Yueyang Tower. The original sentence is: "He must say,' Worry about the world first, and enjoy the world later', which means putting the interests of the country and the nation first, worrying about the future and destiny of the motherland, and contributing to the happiness of the people under the sun, which shows the author's great political ambition.
