Set in China in the early to mid 1800s.
When Snow Flower and Lily were kids, their friendship was arranged by Madame Wang. A contract is drawn up and the girls agree to it and it is supposed to last as long as they are alive. It was a way, perhaps, to give women a relationship that was closer and longer lasting than those of the marital relationship. Because marriages were arranged, love was not a factor and men often took concubines when their wives became older or when the man became bored. So the sworn friend provided that long term, loving relationship lacking in marriage.
The two girls do become good friends and grow up together and when they can't be together, they send each other messages written in the folds of an ornate fan which becomes a simple history of their lives.
At first, it is clear to Lily that Snow Flower comes from a higher status family than her own. Snow Flower's clothes are nicer, her speech and manners more refined and her ignorance of household chores indicates those chores are taken care of by servants. Lily teaches Snow Flower the tasks that Lily performs every day, cooking, cleaning, caring for the elderly and the little kids. And Snow Flower teaches Lily the refinements she has been taught in turn.
Foot binding was common in China at the time. I am not going to discuss a custom that I feel is depraved and barbaric except to say it was part of a young woman's appeal to a potential husband. Because Lily's bound feet were considered particularly appealing, she became the wife of man of higher status and privilege than her humble farming family.
However, even though Snow Flower's bound feet were also considered beautiful, she did not find a high status spouse but instead was married to a butcher. Snow Flower's father was a drug addict and a gambler and he bankrupted his family and a butcher was the best Snow Flower could do for a mate.
It's not surprising that Lily and Snow Flower were not that close, given the disparity in their adult lives. As Lily's fortunes rose, Snow Flower's declined. Add to that the stress of a war that sent the people fleeing for their lives from their villages to shelter in the distant hills. Lily and Snow Flower became more dissatisfied with each other. While Lily wanted Snow Flower to try harder to improve her life and the lives of her family, Snow Flower wanted Lily to accept her and her life for what it was without nagging her to do better. Lily became distraught and cut Snow Flower out of her life. It was only as Snow Flower was dying that Lily came to understand how she had failed her lifelong friend.
This was a fairly interesting story. I have to admit that I hated the way women were treated in it, everything about the coldness and cruelty made me angry and distressed. On the other hand, the Chinese civilization is thousands of years old and apparently that system worked for them, as vile as it seems to me.
This is not a happy story, the lives of the women as described in the book are miserable. They are hemmed about by rules and traditions and limited in every way, even the better off women have very little freedom and very little choice in how they live their lives. Throughout the story, we are reminded that women were viewed as evil and as a burden to the families unfortunate enough to produce them. Such sad, miserable lives and I was not sorry to be finished with the story.
