Of the tens of thousands of Chinese children who are kidnapped each year, are most sold into slavery?

Most are sold into slavery no doubt. The kidnapped girls are sold in big cities like Beijing and Shanghai to work as aayees in rich Chinese households. Majority of kidnapped boys are sold to Chinese triads who either train them to be drug courier, professional beggars etc. Many of these kidnapped children find their way to far away places where they are forced to work as slave workers in Chinese brick kilns.
