In the Tang Dynasty, there was a poet named Li Bai. In his youth, he traveled all over the country and wrote many famous poems. Later, he offended the powerful and was demoted, and he had to leave the capital and return to his hometown. After returning to his hometown, he did not lose heart, but instead decided to start over. He sold his property and used the money to buy books and pens and began to concentrate on writing. He wrote poems and articles every day and sometimes worked through the night. His efforts were rewarded, and he created many more masterpieces, making his reputation as a poet even greater. This story tells us that no matter what difficulties we encounter, as long as we have perseverance and start over, we will surely succeed.
