There happens to be a graduate student among my colleagues here. I ask for your help. The operation is staged and involves a lot, mainly your specific situation. It costs money to increase accommodation and medical treatment after surgery. The situation is good, and you can save about 15000 room and board! As it is in stages, there is no need to get everything ready at once. I suggest you hang a common number at your colleague's office to let the doctor know about your illness and ask about the course of the disease. Ordinary number 7 yuan.
