Ethnic periodicals generally don't have much money, and they weren't expensive when I published them. A few hundred dollars is enough, but it's still early. If you have published papers during the university, you can use them when evaluating professional titles. My colleague published it for several years in college, and you can use it, too. It is worth learning that the price is too low, because it is easy to send electronic publications or sets of periodicals, and it is not easy to use when evaluating professional titles. This thing can be found in the General Administration of Press and Publication. At that time, it was very cheap, belonging to a set of periodicals, that is, books were in brackets. There are several versions, which are said to be unqualified when selected, and are worth learning from. In addition, you can compare several websites. At present, our unit publishes on the paper network, and the online reputation is also very good. If you are confused, you can ask. I wish I could help you adopt me.
