I just checked, and it looks to me like the Chinese is just as ambiguous as the translation.

Thanks for checking!
I agree it does make more sense to talk about people in general here.
Although I wouldn't put it past Guo Changcheng to feel guilty for something that wasn't his fault.


Though of course Wang Xiangyang's blaming the hospital and Zhao Xinci is entirely misdirected

Ha, the one time Zhao Xinci wasn't doing anything, he gets blamed XD


When Lin Jing confronts Sha Ya at the end, is he doing this on his own, or is he part of Zhao Yunlan's plan?

I had assumed (baselessly) that this was Lin Jing acting on his own, but that's actually a good question!
Also, would leaving Lin Jing out make it obvious he is under suspicion, or can it be presented as a kindness?
