"Mr. Jing Qing is elegant and upright" is a honorific, that is, a polite expression. Generally, it is used to write a book or article for others to read, just to tell Mr. Jin Qing.

Yazheng is to modify the article and so on.

For example, my brother is new here and wrote a pair of couplets himself. I sincerely hope Mr. Qing is elegant. Thank you very much.
