Bai Juyi's "Don't cry, sneak away; Don't say' dark acacia'; The whole poem and title of "No one knows outside two hearts"

Don't cry, dive. Nothing to say, dark acacia. No one knows outside the heart.

A solitary bird locks a deep cage at night, and a sword breaks branches in spring. Although the river is turbid and clear,

Aconitum is sometimes black and sometimes white. There is only seclusion and dark separation, and there is no end to each other.
