A marketing trainer in China was sentenced to 11 years in prison for raping nine female trainees under the pretext of helping them "break through mental barrier".
Lu Yu'an, the 45-year-old beauty product marketing trainer in Guangdong province, started offering courses in August 2009.
During the training programme, he allegedly took female trainees to his room.
He would then dare them to take off clothes or even have sex with him to "break through" the mental barrier of communicating with strangers and improve their marketing skills, Shanghai Daily cited Guangzhou Daily as reporting.
A prosecutor said Lu raped nine trainees before he was held.
He also allegedly took naked photographs of three trainees so as to threaten them to have sex with him again.
Some victims said that Lu told them not to share information about the "breakthrough".
