What was Amy Tan's whole purpose of writing The Joy Luck Club?

Whenever we consider the "purpose" of a text, we often
have to infer the reasons that the author had for writing it. However, when we think
about the life of Amy Tan and how her life experience is reflected in this excellent
novel, perhaps we can understand her reasons. Amy Tan herself, like the four younger
characters in this novel, was a person who had to struggle with two cultures: the
culture of her parents who had left China during the Communist revolution and the
culture of the country where she was born, America. Amy Tan herself said that she "grew
up with several Englishes," and just like the characters in The Joy Luck
Club, she had to struggle with the various cultures in which she lived,
especially concerning expectations of her Chinese parents and the freedom and
opportunities given to her in America. Thus we can deduce that this novel was written to
share and communicate something of the experience of Chinese immigrants and their
children and the struggles that they face.
