Why not just use a translation app? , most hospitals have English boards on the counters . First go the card registration counter 1 to 5 yuan , then go to the service counter 1 to 10 Rmb to book a doctor , some hospitals you can book the card and book the doctor at the same counter. Then use a translation app to tell the doctor what you want checked .( i usually check my cholesterol and vitamins and metals, cost about 40 Rmb) The doctor will give you a blood test page and you go pay. Then you go to the blood testing place and they take your blood samples. Later you have to go fetch your blood tests results from the outside the blood test area. Also most of the younger doctors can speak some broken English combined with our broken Chinese than it is enough to communicate .(broken = low proficiency the way the Chinese use to describe their low proficiency in English)
