The English editor (scientific editor) not only polished the English of our manuscript, including grammar, punctuation, and overall readability, but also significantly contributed to the academic expression by providing constructive feedback on the paper's framework, constituent elements, results, and conclusions. This included appropriately compressing lengthy or repetitive sections, suggesting structural modifications, identifying ambiguous passages, rewriting academic descriptions, questioning certain statements in the paper, and offering constructive academic suggestions. All of these insights and assistance have been very inspiring and helpful for us as authors. Thank you very much to the editor.

Thank you so much, LetPub, for providing great services at a very affordable price. I am especially thankful for your efficiency and helpful advice to maximize my article publication chances, even in the most unusual circumstances. I definitely will come to you if I need similar editing services in the future.

The expert editors at LetPub are very professional. We have worked with them twice and both experiences went well. The reviews given by the editors of the journal did not mention the language issue. LetPub's customer service is very good, and the speed of processing articles is very fast, while carefully editing each paper.

LetPub's translation service is very professional, and the reviewer recognizes the language and can provide professional certification.

We had a smooth experience translating our design to beautiful Cover Art using the LetPub Cover Art service. The process was easy. We met with the team, filled out a form, and provided a conceptual drawing to the team. The team made an exceptional draft cover in one week. We requested a minor revision of the draft cover, then it was done. We will definitely use LetPub's cover service again!

We used LetPub’s English language editing service, our paper was revised three times, and each time was very professional and detailed. We contacted the Client Communications Specialist by email throughout the whole process, they answered our doubts patiently, and the processing speed was very fast. Many thanks for LetPub's professional and meticulous service, and it is very helpful for future paper writing.

Before my colleague referred me to LetPub, I originally tried to polish the article myself. LetPub proved that their service is very reliable. The polishing result has also been recognized by the journal that submitted the manuscript. No reviewers found any language problems. Thank you LetPub!

The editor made grammatical changes to the article: such as the correct use of "a" and "the". In addition, the editor also modified the expression. After revision, the article is smooth and easy to understand.
