Which is better, Wang Tan or Zhang Finland, tutor of postgraduate respiratory medicine in Changchun University of Traditional Chinese Medicine?

Teacher Wang Tan's medical ethics is particularly good, not because he is arrogant, but because he is deep and does not like to talk. I am his patient. My illness is difficult to treat, so I can treat it here. Later, I went to prescribe medicine, and he said not to take it yet, because it would be fine if the disease didn't develop, and it would be useless to eat too much. Good medical ethics.
