Greetings!
You might want to start with an introduction that states whether the two types of conflict are essentially the same or very different. Then you would go on to describe each type, giving several examples from the work, using quotations to support your description. Depending on how long the paper is supposed to be, you could include a discussion of the importance of the familial conflict to the work as a whole. I'm not sure about Cages, but it's my understanding that the issue is quintessential to The Joy Luck Club. If you're having trouble getting started, try looking through the books, picking out scenes where the conflict arises, and see if you can arrange them in a logical order for comparison.
I hope this helps!
