Shoyoroku - Case 40: Unmon's "White and Black"

Unmon asked Kempo, 
  "May I ask for your answer [1]?"
Kempo said,
  "Have you ever reached this old monk or not?"
Unmon said,
  "If so, I must say I was too late."
Kempo said, 
  "Is that so? Is that so?"
Unmon said,
  "I thought I was Marquis White, but I find that here is Marquise Black [2]."

[1]: A literal translation. It is possible to understand the word simply as
     "instruction."
[2]: Marquis White and Marquise Black are noted thieves in Chinese folklore.
     Marquise Black, a female thief, seems to have been the cleverer of the two.
