When choosing professional title institutions, we should try to avoid choosing unreliable institutions to evaluate professional titles. Regular institutions will declare their professional titles to people in accordance with the prescribed procedures, help publish papers smoothly, sort out performance data, improve the passing rate of professional title evaluation, and provide professional services, which makes people worry and save effort [2].
If you really need professional title intermediary service, I suggest you choose an intermediary that has been recommended by your friends and has a certain reputation in the industry. This can increase the reliability and trust of the choice.
