Jornal de Pediatria

The OA journal of the Brazilian Pediatrics Association costs 1000 USD. There were very few contributions from Chinese people, so I didn't have much hope, considering it is a journal in the second tier. However, it turned out to be quite fast. I submitted the manuscript in the afternoon and it was under review by the evening. They also provided a link to track my own peer review. It took 2 months to complete the peer review, and the editor was very nice and efficient. I would submit revisions during the day and receive feedback either in the evening or the following day. After one major revision and one minor revision, the manuscript was accepted. Although there was only one expert reviewer for the major revision, they provided a lot of detailed feedback, with a whole 20 pages of word-by-word responses.

Submitted two papers and got accepted for two papers, the process was relatively fast, both were recorded about half a year ago.
