It's an article offering Tips on Becoming a Good Writer that begins as follows:
"As the saying goes, the pen is sharper than the sword. A good writer is able to influence their readers into their train of thought; he or she is able to encourage and motivate the reader, gain their trust, and make the readers practice what they learnt from them. What it means to you that, whether you are aspiring to be a author of a bestselling novel or you are a marketer representing your company products and brand, being good in writing can put you in many advantages."
Chinese proverb: If your words are worthless, don't give advice.
