What are the poems describing "public welfare"?

1. In August and autumn, the high wind howled, rolling up the triple grass on my house. Mao Fei crossed the river and sprinkled it on the outskirts of the river. The highest one hung a long forest tip, and the lower one floated to Shentang 'ao. The children in Nancun bully me, and I can't stand being a thief in the opposite direction, openly carrying Mao into the bamboo. I can't breathe when my lips are burnt and my mouth is dry. When I return, I sigh on my staff. In a moment, the wind will set the clouds and ink color, and the autumn will be bleak and dark. The cloth has been as cold as iron for many years, and jiao er is lying down and cracking. There is no dry place in the bedside room, and the rain feet are like hemp. What's the point of getting wet in the long night? There are tens of millions of buildings in Ande, which greatly protects the world's poor people from all smiles, and the wind and rain are as calm as a mountain. Whoo! When I suddenly see this house in front of my eyes, I will freeze to death alone! (

2. time was long before I met her, but is longer since we parted, and the east wind has arisen and a hundred flowers are gone. And the silk-worms of spring will weave until they die, and every night the candles will weep their wicks away. Mornings in her mirror she sees her hair-cloud changing, yet she dares the chill of moonlight with her evening song. There are no many ways to get to Pengshan, oh blue-birds, be listening!-Bring me what she says!. ("Untitled time was long before I met her, but is longer since we parted" Li Shangyin)

3. Good rain knows the season, and spring happens. Sneak into the night with the wind, moisten things silently. The wild path is dark, and the river boat is bright. Look at the red and wet place, and the flowers are heavy in Jinguan City. ("Delighting in Rain on a Spring Night" Du Fu)

4. What do you want to deliver the canopy, but you dare not turn over and have met. A broken hat covers a busy city, and a leaky boat carries wine. Fierce-browed, I coolly defy a thousand pointing fingers, Head-bowed, like a willing ox I serve the children. Hide in the small building into a unified, regardless of winter and summer and spring and autumn. ("Self-mockery" by Lu Xun)

5. No matter the flat land or the top of the mountain, the infinite scenery is occupied. ? Bees, you harvest flowers to make the nectar, who in the end paid hard, and who want to taste sweet? ("Bee" Luo Yin)
