The difference is that the certificate issued by the National Professional Talents Certification Management Center is printed with the words * * * of People's Republic of China (PRC) and the national emblem with anti-counterfeiting marks. At the same time, the certificate is a vocational skill certificate. Because the qualification certificate was cancelled, the skill certificate replaced the qualification certificate. Certificates are similar to academic qualifications, and all training certificates are inefficient. Relatively speaking, the skill certificate issued by the National Vocational Talents Certification Management Center has higher gold content, and it is also a national official website.
