What is the name of meteor butterfly sword TV drama meteor butterfly sword?

I should ask why the original book was named meteor butterfly sword.

The first chapter of Meteor wrote:

Although the light of a meteor is short-lived, what star in the sky can be more brilliant than it?

When a meteor appears, even the eternal constellation can't take away its light.

Butterfly's life is fragile, even more fragile than bright flowers.

But it always lives in spring.

It is beautiful, it is free, it can fly.

Its life is short but fragrant.

Only the sword is closer to eternity.

The light and life of a swordsman are often on the sword he holds in his hand.

But if the sword has feelings, will its light become as short as a meteor?

He was lying on this bluestone when the meteor crossed the night sky.

This is what Gu Long wants to show. I suggest you read the original, it's quite good ~

And the protagonists are "Meng Xinghun" and "Sun Xiaodie", which also has this meaning in it ~ ~

Answer hope satisfied!
