1. Regular primary and secondary education periodicals will have international standard serial publication number (ISSN) and domestic unified serial publication number (CN). Journals lack these serial numbers, or they can't be found in the official website of the State Press and Publication Administration, which is a fake journal.

2. The publishing information of regular periodicals, including the addresses and contact information of publishing houses and editorial departments, is true and reliable. Fake journals often provide false publishing information, or can't provide detailed publishing address and contact information.

3. Regular journals will have mailing codes, and this information can be found in the post office or the national newspaper distribution network. The postal code can't be found, and the periodical is fake.
