Second

(The discussion between L and I went on.)

I paused for a moment and said, "My friend, if you were talking about hospital discharge summary, your analogy of Scarlet Heart and Palace doesn't quite fit."

To my surprise, L laughed and shook his head, "You are absolutely right. I was actually thinking of something else. The topic of hospital record documentation came up because it was deep in your head."

I must say I was annoyed by this insightful psychoanalysis of my mind, "Well, then, what's in your mind?"

"Alas, I was pondering about the rights of derivative works (二次創作)," my friend sighed.

"You mean, one of them is copying from the other?" I was curious.

"No, I mean both are copying from a common source - for example, Zhao Erxun (趙爾巽)!" said L.

PS. For those who are not familiar with Chinese history, Zhao is the chief editor of The Draft History of Qing (清史稿).
