The following conversation took place by the lake.
Tang Thirty-Six could faintly see iron-like black hairs on Xuanyuan Po's right arm and asked, "Black bear?"
Xuanyuan Po glanced at him and knew that this question had been asked without malice. He replied, "Bear."
Tang Thirty-Six went, "Oh, it really is a black bear."
(TN: 'Black bear' can also mean 'coward'.)
Xuanyuan Po seriously pondered the difference between a black bear and a bear and confirmed that he was being made fun of. He noted, "Tang Thirty-Two, you are not a good person."
Tang Thirty-Six's face turned somewhat unsightly. "I said before, don't call me Tang Thirty-Two."
Xuanyuan Po was very stubborn. "Tang Thirty-Two, didn't you say that we should call you whatever rank of the Proclamation of Azure Sky you were?"
"That was for the sake of motivating myself."
