The swallow finally came back. What did he write at last? I remembered this poem.

1, Swallows fly in the mud, Yuanyang sleeps in the warm sand-Du Fu's quatrains

This small building belongs to Yan and dusk. Loneliness locks the high door. Breeze and drizzle, precious flowers and vernal equinox. -From: Du Anshi's Youth Journey

Last year, I left my nest and said goodbye to my neighbor. Today, I was stunned by the new thatched cottage. Bloom should ask each other about the language, not the village master. -From: Wei Zhuang's "Yan Lai"

4. Swallows fly to see the painting building, and the jade hook hangs the curtain. -From: Ouyang Xiu's Linjiang Fairy

Swallows know where they are, but the moss is deep and crooked, and the grass is black and oblique. -From: zhangyan's high balcony

6, deja vu, Yan returned, the small garden fragrant path wandered alone-Yan Shu's "Huanxisha"
