The border warden at E requested to be introduced to the Master, saying, "When men of superior virtue have come to this, I have never been denied the privilege of seeing them." The followers of the sage introduced him, and when he came out from the interview, he said, "My friends, why are you distressed by your master's loss of office? The kingdom has long been without the principles of truth and right; Heaven is going to use your master as a bell with its wooden tongue."
