<span style="text-decoration: underline;">Dear editor,&nbsp;<br /><br />Thank you very much for turning around my work for many many times! You may feel familiar with this document because you have edited the manuscript before. It is a&nbsp;review manuscript. I revised the&nbsp;discussion and conclusion sections and need your help to improve it in terms of grammar, word of choice, flow and readibility.&nbsp;<br /><br />Thank you very much!<br /><br />NC<br /><br /><br /></span>
