Don't take seriously what you are fighting for in the firelight. What do you mean?

It means: life is spent in an instant, and you don't have to be serious about a small matter as big as a snail's horn.

"What happened in the firelight? Dwelling in a humble abode is from the poem Five Drinks by Bai Juyi, a poet in the Tang Dynasty.

The original text is:

What happened to the snail's horn? I sent this body into the fire of stone.

Rich and poor are happy together, and it is an idiot not to laugh.

This poem poeticizes the allusions in Zhuangzi. Zhuangzi once said a fable: Snails have two horns, one is the left foot kingdom and the other is the right foot kingdom. There was a dispute between the two countries, killing each other, lying dead for thousands of miles, bleeding like a river, and the phone call was only the size of a snail's head.

Bai Juyi used this allusion to advise the world not to pursue fame and gain for a trivial matter.
