Help me write a poem about butterflies.

Hu Shi, a famous writer, wrote a poem "Butterfly" in August 2006, which was included in the Collection of Attempts. The content is as follows:

Two yellow butterflies, both flying into the sky.

For some reason, one flew back.

The other, lonely and pathetic.

I have no intention of going to heaven. It's so lonely.

This article seems naive, but its significance is epoch-making, because it is the first vernacular poem written by China after he practiced vernacular Chinese.
