Why are there two poems in Wang Wei's Farewell?

Meet sb. leave

Please have a drink with your horse and ask your friend where you are going.

You said you would go back to Zhongnanshan because you were not proud of your life.

Just left, I want to ask again, look at the white clouds floating.

Meet sb. leave

Author: Wang Wei Age: Tang School: Five Unique Categories: Farewell

Seeing friends off in the mountains, Chai Men is half hidden at sunset.

Spring grass is green every year, but what about you, my friend Prince? .

Different environments, different characters, but the scene and artistic conception are almost the same. It's all farewell, so it's all farewell.
