You can't. China Journal Network, also known as China HowNet, is the largest academic paper database and academic electronic resource integrator in China, which contains a large number of academic journals, dissertations, conference papers and other academic resources. The papers collected by China journals online can be used as one of the reference bases for the evaluation of professional titles, but they cannot be directly used for the evaluation of professional titles. Professional title evaluation usually needs to meet certain conditions and standards, including the quality, innovation and academic influence of the paper. The accreditation body will review the applicant's thesis according to the specific requirements for professional title accreditation. Therefore, the papers collected by China Journal Network cannot be evaluated for their professional titles.
