Let me just link you actual scientific literature and articles on the gender inequality and gender imbalance in China. Anecdotal source, I am actually an Asian woman from a culture that prefers male children.

Most notably: "The tradition of son preference, however, has distorted these natural sex ratios in large parts of Asia and North Africa. This son preference is manifest in sex-selective abortion and in discrimination in care practices for girls, both of which lead to higher female mortality."
