Professional title evaluation depends on where the certificate is issued. Generally, the professional titles issued by Ministry of Human Resources and Social Security are the most recognized. Secondly, all central enterprises and state-owned enterprises have professional title evaluation qualifications, and the general internal review is not external. Thirdly, some societies and trade associations have issued qualifications, which are generally recognized in the industry.
Of course, many of them are sent by themselves, but there are no recognized units. Of course, this is a fraud. You'd better ask the company what kind of professional title is recognized by the company, and then you can choose where to evaluate it.
