Balzac & the LCS

At the beginning of Balzac and the Little Chinese Seamstress, the LCS is an uneducated girl(for she was taught be her father) and is "not civilized, at least not for me!( Sijie 27) according to Luo. Not only that, she is a country girl who has no knowledge of the outside world. Ironically, the beauty of this "uncivilized girl" captures Luo's heart, and his reading's has "educated" her causing her to venture out into the world. Not only does she have the audacity to leave without telling anybody, she tries to erase who she is and where she comes from, by make herself seem more 'citified'. But why does the novel end with her leaving, most likely, her first love, without telling her father she going, or without telling the narrator who had helped her beyond measures? Is it her new found knowledge and her "beauty" that is a "treasure beyond price", that gives her a new arrogancy? Or does she use her new found knowledge in a positive way to really go out and explore the world that has been hidden to her for so long? The author could have ended the novel this way to show how much of an impact Luo actually had on the LCS. Nobody would have ever guessed that the LCS would change who she was and attempt to leave her country lifestyle. She would be using her beauty to help her get through the western culture as oppose to the Chinese culture.
Another bit of irony is the fact that Luo and the narrator are sent to get "re-educated" or to have the western culture 'erased' from their minds, and yet they still find the western culture through literature and influence the LCS in the process. Once he found the books on Western culture, he even exclaimed that "with these books I shall transform the Little Seamstress. She'll never be a simple mountain girl again." (Sijie 100) Yes, he indeed transformed her, and in a way his plan backfired.
