Dear Xuaying,
I am terribly sorry to hear that you are suddenly ill and hospitalized. I do feel much worried about your helath when I get to know that you received an operation last week. I hope that you have enough confidence to get over the illness since in my mind you are always a girl of strong will.
With the advanced medical facilities and experienced doctors in Xinhua hospital, I am convinced that you will soon recover. You know, your co-operation with doctors will be of much importance. I will come over to see you the other day and send you short messages via mobile phone every day. Wish you a quick and complete recovery.
Yours truly,
