No, you're right, I have no idea how I missed the actual line when I was talking about the meaning of the line ... It does seem to mean literally extrajudicial mercy. Sorry! Hm, then how does that go together with Shen Wei starting out invoking Dixing's rules? Maybe he means he doesn't need to invoke the law? I wish I understood more Chinese!

And no worries, it should have been clear from context. I don't seem to have been very awake writing my comment yesterday!
