Bright Educator magazine is not the core magazine. Generally speaking, "national" periodicals refer to periodicals sponsored by the Central Committee of the Communist Party of China, the State Council and their subordinate departments, China Academy of Sciences, China Academy of Social Sciences, democratic parties and national people's organizations, and periodicals of national professional societies. "Provincial" periodicals, that is, periodicals sponsored by provinces, autonomous regions and municipalities directly under the Central Government and their subordinate ministries, commissions, departments and bureaus, and journals (periodicals) sponsored by colleges and universities. The so-called core is a periodical with high quality, good economic and social benefits and key support from the national government. 2 1 1 project equivalent to university education. Of course, it is the national core cow! I hope it helps you.
