Lin Fan said, "I don't think I told you, Uncle, that I studied medicine, so I'm quite observant. Although you're trying hard to act normal, your complexion has betrayed you. You're injured."
Uncle was taken aback. Lin Fan was a doctor.
"I couldn't tell that the young fellow, being so young, is actually a doctor. You're able to easily identify my injury; your medical skills must be quite good." Uncle said.
Lin Fan replied, "It's passable. Uncle, do you mind telling me why you and your friend were talking so intensely?"
Uncle chuckled and said, "It's nothing. We're old friends, just sparring a bit."
Lin Fan asked, "So are you done sparring, or do you still want to continue?"
Uncle said, "Done. We're just catching up, I can't move anymore."
Lin Fan replied, "I think not, Uncle. You seem quite tense. Sorry, as a medical student, I enjoy observing patients' demeanor."
