《太平广记·卷二百六十八·酷暴二》
唐朝时的殿中侍御史王旭，搜括自己家及别人家的女子当宫妓，有不肯承当的，便用绳子勒她的阴部，然后叫壮士用竹棍击打。使那些不顺从的女子们疼痛得难以忍受。
唐殿中侍御史王旭，括宅中及别宅女妇风声目色，有不承者，以绳勒其阴，令壮士弹竹击之，酸痛不可忍。
Wang Xu, a secretarial official in the government, plundered women from his own family and from others to be palace concubines. Those who refused were whipped with ropes to the extent of vomiting blood, and then handed over to a eunuch with a thick penis to rape.  The women were so badly hurt that they were unable to endure the pain.
