When submitting a manuscript, there should be a complete contact information at the back of the manuscript: the author's name, signature, address, telephone number, email address, QQ, etc., so that the editor can contact you! If you don't have these, it's hard to find you for your article.
To submit a manuscript by e-mail, you have to indicate which column to vote for, and write down your name and the title of the manuscript.
Before writing a manuscript, you should know more about and study the magazine you contributed. Including magazine positioning, plate situation, target population, column style, column setting, word count, etc.
