Joy Luck Club "Scar" and "Moon Lady" response

To me, this book is really starting to get interesting. In the story "Scar", Amy Tan wrties about a girl that has a really mean grandmother, or mother I'm not one hundred percent sure which, named Popo. Popo keeps putting things into the little girl's mind that the girls mother was disgraceful towards their family and that she's never allowed in the house again, for being married to a married man, and for being a concubine. The reason this story is called "Scar", is because the girl explains that she got a scar on her neck when she was little because Popo made her spill hot water on her neck, and when the girl's mother came back to get her daughter, she rubbed her daughter's neck to check if she still had the scar on her neck. The next story, "The Moon Lady", is about a girl that's living with a family that really doesn't care about her very much. Also, she is being instructed by the Moon "Lady" that girls are always supposed to listen, and never ask questions because that's the only thing women are good for. I was very surprised at the ending of the story, when the moon lady took of her mask, and insted of seeing some old woman, the moon lady was actually a man in desguise. I'm really starting to get pulled into the "Joy Luck Club", and I think that this story is very complicated, but now, since the peices are starting to come together, everything makes a lot more sense.
