There are many famous sentences in China's classical poems that express the meaning of self-improvement. Please give an example and talk about its significance.

Song Dynasty: Su Shi

The old man talked about the crazy years, pulling yellow on the left, holding pale branches on the right, wearing a gold hat and mink, riding a thousand horses to roll the flat hills. In order to repay Daocheng, I followed the satrap and shot a tiger to watch Sun Lang.

After drinking wine, my chest is still open and my temples are slightly frosted. What's the harm! When will the emperor send someone down, like Emperor Han sent Feng Tang to the cloud to pardon Shang Wei? I will make my strength as full as the full moon, full as the full moon, heading northwest and shooting at the team in West Xia Jun.

Translation:

Let me express the lofty wishes of young people. I held the yellow dog in my left hand, held the eagle high in my right hand, wore a colored hat and mink coat, and swept the flat hills with my entourage.

In order to repay the whole city for hunting with me, I will kill the tiger myself like Sun Quan. I drank wine, my mind was broadened, my courage was more heroic, and my temples were slightly white. What are the disadvantages?

When will the emperor send someone down, just as Emperor Wen of Han sent Feng Tang to the clouds to pardon Shang Wei and trust me? At that time, I will try my best to pull the carved bow like a full moon, aiming at the northwest and shooting at west Xia Jun.

2. "It's hard for me to go"

Tang Dynasty: Li Bai

The cost of pure wine is a gold cup, 10 thousand copper coins and a hip flask, and I am ashamed of 10 thousand yuan.

I threw the food bar and cup aside. I couldn't eat or drink. I pulled out my dagger. I peeped in four directions in vain.

I want to cross the Yellow River, but ice will block the ferry and Taihang Mountain will be covered with snow.

I will sit on a fishing rod and lean lazily by the stream, but I suddenly dream of sailing a boat towards the sun.

Travel is hard. Travel is hard. Don't go astray! Where to go today.

One day, I will ride the wind and waves, raise the Yun Fan and cross the sea.

Translation:

The wine in the golden cup 1000 yuan a barrel, and the food in the jade plate 10000 yuan.

Depressed, I put down a cup of chopsticks and didn't want to eat it; Pulled out his sword and looked around, feeling at a loss.

I want to cross the Yellow River, but the ice and snow have frozen the river. If you want to climb Taihang Mountain, that mountain has been closed by heavy snow.
