What burden does Jing-Mei carry?

In “Two Kinds” by Amy Tan, Jing-Mei carries several burdens. As a child, she internalizes her mother’s sadness about losing her twin daughters and husband in her native China. She tries to please her mother by acquiescing to her belief Jing-Mei can be a child prodigy. When, after a disastrous piano recital, this dream does not become a reality, the daughter argues with her mother, creating a rift in their relationship.
 Jing-Mei lives with the aftermath of that argument, and becomes a rebellious, self-centered daughter.  During her school years, she is a mediocre student and forges her own identity despite her mother’s feelings.
She carries the feelings with her even after her mother’s death until she resolves her inner conflict while playing the piano that was integral to her perceived failure as a daughter.
