What does it mean to be old and strong, not to grow old together, but to be poor and change, and not to fall into the sky?

Although you are old, you should be more ambitious. How to change your mood when you are old? Although the situation is difficult, we should be more ethical and never give up our lofty aspirations. This poem comes from Wang Bo's article "Preface to Wang Tengting". Only a gentleman knows the opportunity, and a prudent man knows his own destiny. Although you are old, you should be more ambitious. How to change your mood when you are old? Although the situation is difficult, we should be more ethical and never give up our lofty aspirations. Even if you drink from the fountain of greed, you still feel refreshed, and even if you are on a dry main road, you are extremely happy. This sentence is sincere and full of emotion, true. It shows the heroic ambition of the poet to serve the country and establish a reputation. This is very inspiring and has become a famous motto that will be told to future generations.
