One is the initial inspection and the other is the re-inspection.
In order to ensure that the new employees of the railway bureau are suitable for work, a physical examination will be conducted. The purpose of initial inspection and re-inspection is to eliminate potential diseases so as not to affect the work. The initial examination is organized by the Railway Bureau, which mainly checks routine items, such as height, weight, vision and blood pressure. Re-inspection is organized by the hospital to review the items with problems in the initial inspection to ensure the health of new employees.
