However, several problems posts challenges to accessible and affordable hospital healthcare. To begin with, prices of medicine are set unreasonably high to make up for low service price. Doctors are also dissatisfied about their income.[12] Secondly, great tension in patient-doctor relationships sometimes causes conflicts or even violence against doctors (yinao).[13] Furthermore, patients are not distributed by seriousness among hospitals and lower health facilities, which leads to over-consumption of high-level medical resources in hospitals.[14]
