"My heart is like a tiger, smelling roses." What do you mean?

Translated by Yu Guangzhong, there are often:

"There are tigers in your heart, sniffing roses; After the banquet, I burst into tears. "

First reading, puzzled; Word by word, I still don't understand why. Memories in my mind, just in an accidental moment, suddenly silent, as if I realized something.

Perhaps, everyone has a tiger in his heart, so there are often times when he is brave and firm, but there are still roses outside the den. Therefore, no matter how cruel and passionate you are, there are still weak lotus flowers blooming in your chest.

The two opposite extremes, one is rigidity and the other is flexibility. Therefore, we can't live without the courage of a tiger or the delicacy of a rose.
