The editorial office will use scientific journal Academic Misconduct Literature Check (AMLC) system for plagiarism test, and manuscripts that do not meet the requirements will also be rejected.
3. External Review: Manuscripts that pass the initial review will undergo anonymous double-blind peer review，conducted by at least 2 reviewers. The manuscript will be sent to at least two reviewers for external review. The editorial office will make textual edits to the manuscript. Revision comments will be communicated to the authors via email. Authors must respond to each reviewer comment and submit a revised version of the manuscript. This process will be repeated until the reviewers and editors are satisfied with the manuscript.
