I dont know anything about the Chinese Charts. But when I was reading up on trying to concieve with my first child I really wanted a girl as well. I found out that Boy Swimmers are faster and Girl Swimmers are slower but last longer. So if you want a girl have sex the day before you ovulate and for a boy the day of ovulation. But to be all honest I wanted a baby so bad that we had sex the day of ovulation as well.
We had sex the day before ovulation and Success! We had a Girl! I used the clear blue easy ovulation test kit to know when I was ovulating. We will be trying for baby number 2 pretty soon and I want another girl...this will be our last child. I was going to let nature decided but I think I will help like last time.
Good luck and update the post when you do get preg. and find out what you have.
