Thoughts and predictions on the rest of the novel based on the title of the novel and the story The Kitchen God

The story of the Kitchen God tells the story of a man named Zhang who had everything he would ever need including an amazing wife named Guo, the woman who gives Zhang his wealth.  Zhang decides to give up his wife because he became greedy and selfish.  Zhang loses everything after that, and then is saved by his wife.  When Zhang realizes his mistake, he kills himself.  This is understood as courageous because he admitted his wrong.
If the story of the Kitchen God is a parallel story to the novel "The Kitchen God's Wife," then the two stories must share similar plots and/ or characters (character in the stories share similar personality traits).  Since the novel is about The Kitchen God's wife, I predict that Guo, the wife of Zhang, shares similar personality traits with one of the characters in the novel.  In the story, Guo works hard and then receives some bad luck: Zhang leaving her.  After her bad luck, she still takes care of the people who have hurt her.  So far in the novel, Amy Tan wrote that Whinnie, Pearl's mother, started her life in her loving mothers arms with everything she needed.  Then, her mother died, Whinnie's bad luck.  In the present time, Whinnie tries to take care of Pearl  her daughter, even though Pearl doesn't always appreciate her mother.  Guo and Whinnie seem to be similar in how they act.  Could Whinnie be the "Kitchen God's Wife?"
