A man visits his sick friend, and finds him to now be well and energetic. “How wonderful!”, his friend says, “What happened?”
. “Dr. Chang is the cause of my health.”, he says gratefully.
“Dr. Chang, what did he do?”. “Well, Dr. Li came and gave me a special diet.
And I got sicker.
Then Dr. Wong came and gave me bitter herbs, and I got even worse. On death’s door I called for Dr. Chang.”
“And what did Dr. Chang do?”, his friend asks in wonder.
The man replies happily, “Dr. Chang did the best of all, he didn’t come, so I got well!”
