Question 1:If I had created this article first, I would like to have a brief introduction of certain object, then introduce the detail one by one to satisfy the all kinds of readers. By the way, pictures were needed as well if I can provide. I will also cite the reference for the detail from other people's opinions. Question 2:If I were the second reader, I would like to add the history of certain items in detail or compare the effects of it with similar items. If I realize something that something is missing, I will write them done. Reference list is needed if I can fill more.
