The brother, who is the author of the story, who suffers from some sort of illness that is affecting his brain, is getting no real treatment and doctors do not know what to do to help him. This shows how far behind the times china was at this point.
Another historical context brought to light is cannibalism. Cannibalism is a major topic throughout the book and is a part of the history of China. During the famines it is thought that cannibalism was practiced as a means of survival. The madman writes that he feels the people around him look at him like something to eat and the books he reads all say cannibalism is the answer when one reads between the lines.

Travel is a minor topic covered, but they do talk about getting word from other villages by messenger and the author was forced to travel out of his way to meet with the brother only to find out that the one who was sick had recovered. There is little advancement in technology along with medicine that creates prevalent issues throughout this
