Don't assume a title means a raise: first ask whether your employer appoints within a position quota, or whether a title doesn't guarantee an appointment

In plain words

A professional title is a basis for hiring, evaluation and promotion, but being rated and being appointed are two different things. Public institutions (事业单位) generally rate within a position quota, and once you are rated you will mostly be appointed. An employer that does not run a position-management system can separate rating from appointment, so you may be rated and the employer still does not necessarily give you the matching position and pay. After changing employers or places, your title may have to be re-evaluated or confirmed.
