These words put themselves in others' shoes, thought of the sufferings of the people, and put forward the ideal of making the poor "all laugh". This poem has a pleasant feeling, a broad realm and a loud and powerful voice. From the poet's own painful life experience, he expressed his unrestrained passion and ardent hope, which has been exciting readers' hearts for thousands of years. The sentence "Andrew" is an imagination you want but can't get. The "Great Shelter" is completely covered and protected. "Poor scholar" originally refers to poor scholar, and here refers to all poor people.
