Tell us why we should not be afraid of being late in learning. The principle that Shi Kuang teaches in admonishing students is that age has nothing to do with learning. What matters is the attitude of being willing to learn and being diligent in studying. Even if you are old and love learning, as a young person you should study hard. This allusion comes from "Shuo Yuan" by Liu Xiang of the Han Dynasty, also known as "Xin Yuan", which tells the story of Jin Ping Gong seeking advice from Shi Kuang. In this story, Shi Kuang told Duke Ping of Jin: Being older is not an obstacle to learning. As long as you have perseverance, confidence and determination, persist in the attitude of living and learning until you are old, and always have a love for learning. If you keep your heart in mind, you will definitely succeed. As the saying goes, ambition does not depend on your age, live until you are old and learn until you are old. As long as you have goals, perseverance, confidence, determination, and a love for learning, you will definitely succeed. Age has nothing to do with success. That's why we have this saying: "There is a road to the mountain of books, and hard work is the path; there is no limit to the sea of ??learning, and hard work is the boat."
