What's the poem about "The Blue Witch"?

The poem "The Blue Demon"

The blue demon opens

but you can't see it

Just as I can't walk into your sight

Blue petals

are rolled into tea at night

I am used to drinking this sleepless

ups and downs

swimming through the darkness

. Benevolence's lightning

everywhere the blue enchantress blooms

I can't be spared

This secretly stinging love

The reason why I'm afraid of blue. I finally found out that

the blue enchantress in the dark

is heartbreaking

The strong tea is exhausted

and it is doomed to be sleepless every night.
