It's different. According to official website of the Chinese University of Science and Technology, doctoral students who have completed their master's degrees are more mature and confident, at the same time, they are more excellent in scientific research ability and experience, and more independent, mature and skilled in drawing up scientific research plans and applying for scientific research projects. However, you can graduate one year ahead of schedule, and you can only finish your master's thesis, take part in the defense, and get a master's degree before studying for a doctor's degree.
