Where do the poems welcoming friends come from?

1. The Journey to the Tang Dynasty: Du Fu, north of me, south of me, spring is in flood, day after day I have seen only gulls. The old lady did not sweep the flower path for the guest, today only for you, this chai men has not been opened for you, today for you to open. Far from the city is too far from the good dishes, the family is too thin, only the old wine. If ken invites the old man in the next door to drink together, he will drink his cup through the fence!

2, "Hakka Cong" Tang Dynasty: Du Fu, a guest from Nane, left me with a spring of guest beads. There are hidden words in the beads, so you can't distinguish a book. Keep your mouth shut for a long time in order to meet the needs of the public. Open your eyes and turn them into blood, and mourn for the absence of this levy.

3. There is a guest in Wan Li at the door. Wei and Jin Dynasties: Cao Zhi, there is a guest in Wan Li at the door, and he asked where you came from. From the beginning, you will be loved by your heart. Wan Shang cried to me, and she was too sorry for herself. Originally a scholar of Shuofang, he is now Wu Yuemin. I will go back to the West Qin Dynasty.
