These [boys being groomed as prostitutes] are sold by their parents (sometimes stolen from them), about the age of 4, and educated, while they are also subjected to a special physical training, which includes massage of the gluteal regions to favor development, dilatation of the anus, and epilation (which is not, however, practised by Chinese women).
