As I re-read the four assigned short stories in Ha Jin’s The Bridegroom, I noticed a series of repeated elements within each tale, as well as linking some of the narratives together.  These appear to be intentional details not needed to describe the scenes, but included deliberately to enhance the depth and complexity of the writing.  The numbers beside each reference below indicate the page on which it is found.
“Saboteur”
Tying germs, hands, foods, and illness together, Jin gives us abundant clues before exposing the final sickness of the plan.

Number Four is frequently used as imagery for four points of the compass, four elements of nature, or Revelation’s Four Horsemen of the Apocalypse who wreak destruction on humanity.  More specific to China, four is considered unlucky since the pronunciation of the number and the word for death are similar.  It is also widely known that Buddism is based on Four Noble Truths:  
          Suffering (including sickness, death, and   
          unpleasantness)
          Origin of Suffering (sin and mental states leading 
          to evil actions, such as desire, hatred, ignorance and 
          misconception of the nature of things)
          Cessation of Suffering (“Nirvana”)

          state of Nirvana)

Apples
Apples are often symbols of temptation from the fall of man in the Garden of Eden (even though the fruit is not named in Genesis), as well as the epitome of American culture.
Can you think of places where apples are mentioned in these four stories?  Here are some hints:
Apple tree shaking
Apple-faced girl
Adam’s apple
