Generally, there are the following situations:

1, your article is very good, but it doesn't conform to the direction of the journal. The rejection letter explained that their journal didn't include articles in my direction, but he thought the articles themselves were quite good, because there were some grammatical defects, so he helped me polish them manually from the editor's point of view and attached them to the rejection letter, suggesting that I vote for another journal (the two journals belong to different associations, purely for your own good).

2. Will support new magazines. Editors will reject manuscripts whose research direction is not so novel, and then suggest that you submit new journals that have just been published for one or two years.

I was rejected by a top magazine in the industry, and the editor suggested that I switch to an unknown new magazine. I looked up the information in that journal, and there was very little. This is a magazine that has just been published. Although it is under the banner of ACS, it is neither a SCI journal nor an impact factor. This kind of article doesn't count when calculating IF at graduation, and it didn't vote in the end.
