We alllll worry about our beloved children!!! So, I prefer to "believe" those "news". It's a good reminder for all parents. When I'd been to Guangzhou last year, all mothers stayed as close as possible to monitor their children. It reflected that there're not just rumours.
I had "lost" my daugther for 5 mins in front of my home gate (village house). That experince made me never ever forgot!!!
