"I'm here to take your pulse and diagnose you," Lin Yifan answered.
He had long guessed that his father would be surprised since he had never studied medicine before, and now, seemingly expertly, he was taking pulses and diagnosing illnesses, which would surprise anyone.
"You know how to diagnose? When did you learn? How come I don't know about this?" Lin Tianwen asked curiously.
His son had returned from his trip a completely changed person, to the point that he barely recognized him.
"I learned it a few months ago; of course, you wouldn't know," Lin Yifan replied, and then he admonished, "Okay, Dad, relax your mind now. Don't think about anything; I'm going to check your body."
Although Lin Tianwen didn't know if what Lin Yifan was saying was true or false, since it was his son who had suggested it, he would just go along with it.
He was curious to see whether his distinguished son actually possessed any medical skills.
