Wei Zilai Shu Fangzhai, what is the poem read by the swallow?

The birds quickly stood in a row.

Sing in your heart and smile in your mouth.

Welcome Wei Zi to the palace.

Bitter grievances are over.

Flowers bloom from this heart

I'm sorry about that bird.

Flowers are no longer sad.

Wei Zijin lock is fine.

Swallows laugh with them.
