To authors and reviewers:
During this special period, the editorial department implements a flexible working system, the office phone is temporarily unanswered, issues related to manuscript review, publication and issuance issues, recruitment requirements, confirmation of proofs before publication, and other related issues. Please contact us by email. Email address : Tsgzz@ibnet.sh.cn. For other contact information, please refer to "Contact Us" in the navigation bar of the website. During this period, the editorial department will normally perform all tasks such as receipt of manuscripts, manuscript processing, editing and proofreading, confirmation of author proofs, online publication and post-publishing articles.

In addition, since the typesetting and print companies have not yet resumed work, official publication will be affected. The editorial department will use the online pre-publishing of the journal, the latest accepted post, online publishing from the media, and pre-publishing by HowNet.

Sincere thanks to the authors and reviewers for their continued support and help to this journal!
