I don't know. It is generally not recommended to find a paper agency to send articles. There is no need for middlemen to earn the difference, and some people send them to fake magazines because they don't understand. I chose an intermediary to publish when I was in a hurry. I posted it three months after it was published in Tao Tao Paper Network to Express. If it is not urgent, I usually submit it myself. Are you satisfied with my answer? If you are happy, adopt it.
