When Feng Gong's friend had a car accident, he met his friend's nanny, Meng Zhang, and Meng Zhang claimed to be a big fan of Feng Gong, hoping Feng Gong would sign and leave his contact information. Finally, he asked for a photo. Although Feng Gong didn't want to at that time, he left his contact information in order to keep abreast of his friends. Even after that, nanny Meng Zhang extorted 500,000 yuan from Feng Gong, and with the intervention of the police, the nanny was arrested for extortion.
