If I choose the publication support service package, does it mean that my paper will have a 100% chance to get published?

No legitimate publishing service providers can guarantee 100% successful publication. Successful publication is subject to a range of factors: the content of your research, the considerations of the journal editors (the journal's aim and scope, the materials of submission, the novelty of your research, etc.), to name a few. Our publication support service will help you understand and thus observe the requirements of your target journal, and provide professional language polishing and pre-submission review to enhance your chance of successful publication.
