Thank you for your pen and ink. Your message adds a lot of color to my article. Literally speaking, the word "stay in ink" means to leave Mo Bao, that is, to write down words. Ancient literati often used pen and ink to write, so it was called leaving ink. "Adding fragrance" originally meant that young and beautiful women accompanied the readers when they were studying in ancient times, and adding fragrance meant increasing. Here, it means leaving Mo Bao to add luster to the article.
