1, Li Bai is hard to walk: One day I will ride the wind and waves and sail straight up and cross the deep sea.

2. Zheng Xie Bamboo Stone: I insist that the green hills are not relaxed, and the roots are broken. After thousands of tortures and blows, it is still strong, whether it is the southeast wind or the northwest wind in winter, it can bear it and will still be tough and straight.

3. Lu You's Reading on a Winter Night: The ancients learned nothing, and it takes time to get old. What you get on paper is so shallow that you never know what you have to do.

4. Wang Zhu's diligence: Learn from diligence and learn from thousands of books. Three winters are enough for today, and whoever laughs is empty.
