 Chen later recalled that his survey would have been significantly larger in scope were he not limited by a lack of financial resources.Though Chinese central authorities have sought to curb the coercive enforcement of the one-child policy since 1990 by replacing measures such as forced abortions and sterilizations with a system of financial incentives and fines, Chen found that coercive practices remained widespread, and he documented numerous cases of abuse.One of the women he interviewed in Maxiagou village, 36-year-old Feng Zhongxia, said that local officials detained and beat her relatives, and indicated they would not be released until she turned herself in and submitted to a forced abortion.
