PS: Still undergoing revision---
Actually, Yang Ping really detests these matters. Since Ivan doesn't want to make additions, let's just follow Ivan's lead.
Plus, Ivan has his own reasons. For plastic surgery patients, it takes much more time to familiarize oneself with their condition and create a preliminary surgery plan, which means more time is spent examining the patients and communicating with them.
"Professor Yang, how could I dare to ask you to add more appointments? That would be too much trouble for you. I just came here today to ask a question. Isn't Ivan suspending his services? Do the appointments that have already been given out still count?"
Director Kong is a very shrewd man. He knows Yang Ping's character well, so he would absolutely not force him to do something against his will. He has his ways.
