Originally it was a lecture, but now it had turned into a question and answer session. Lin Feng's every explanation won him enthusiastic applause, as he always managed to articulate the profound knowledge of traditional Chinese medicine in simple and understandable terms, even for those with no medical background.
"Teacher, I'm asking for a friend," a student asked loudly, "he suspects he has kidney deficiency but is too embarrassed to see a doctor, so he took tonic medicines on his own. Instead of getting better, he ended up feeling even more inflamed."
"This student, I hope you're not making up a friend." Lin Feng started with a joke.
"Hahaha…" The students laughed good-naturedly.
Lin Feng raised his hand, and the students quieted down. He responded, "I haven't seen your classmate, so I can't diagnose by appearance. You just answer what I ask, does his face and hair get oily easily?"
"Yes," the student replied, slightly surprised.
