What is the author's style in Monkey by Ch'Eng-En Wu?

The story is told in third person in the past tense. The author gives the reader a point of view that is both limited and omniscient. It is omniscient when it is necessary to give the reader a clear view of the intentions and meaning of what is occurring. For instance Pigsy and Monkey are often playing tricks on each other and planning them out in their heads. When they go to the city of Crow-cock, Monkey tricks Pigsy into going down into the well telling him there is a treasure to retrieve when in fact it was a dead body. On the way back the author gives the reader insight into Pigsy's thoughts so the reader will be aware of the trick that Pigsy is planning for Monkey when they return. The plan unfolds so quickly once it starts that the reader would have had a hard time realizing what was happening had the author not given some insight into the thought process.
