What do the apples and oranges in Chigang River mainly talk about?

On the train, I met a country girl with dry hair and disheveled clothes. On the way to be a maid by bus, she tried to open the window in order to give her golden oranges to her brothers who came to see me off. According to relevant public information, in this article, the author abandons the historical legends and dark writing language style used in the past and completely turns to describe the whole story from the front according to his own personal experience. The author observes carefully, grasps the small fragments of the journey, and uses line drawing to describe the protagonist, my fatigue and boredom, and the little girl who has a beautiful heart despite her rags.
