Lu Po wanted to tell Cheng Li, I'm sorry, I shouldn't have called you a faggot. Sorry for not treating you gently, I'm sorry that I have such a bad temper and am always rude to you. However, he could only say these words to the bird that chirped on the tombstone in front of Cheng Li's grave. My love, it is deep-rooted, but it never sprouts.
