Emperorapos;s son-in

Today, it should have been a day for my esteemed teacher to impart knowledge and answer questions. Yet, I don't know what has happened, but he seems so enraged!,"Do you know, my son has a congenital heart defect… I've long wanted to give him a new heart, but unfortunately panda blood is very difficult to match with other hearts!","Doctor, what are you going to do... I'm afraid, Ning Ning is afraid."。
