The price of publishing a paper is generally unknown, especially if you are self-funded, so magazines generally don't tell the price before hiring, only the price that needs to be paid after hiring.

Regular periodicals in China can be found in the State Press and Publication Administration. As long as you can't find them, be careful. Then see if the three databases (HowNet, VIP and Wanfang) are updated normally. If they update normally, then there is no problem with the arrangement. If the temporary update is abnormal, then you need to pay attention and ask for details. Check the manuscript in time after employment, and check the manuscript by telephone through the editorial department of copyright page.
