“I rarely talk with my parents or grandparents,but I talk a lot with my old friends on QQ,” said Fox’s Shadow, the online nickname used by a Senior 2 girl in China. “Eighty per cent of my classmates use QQ after school.”
QQ is the biggest messaging service in China. A record 4 million people used it one Saturday night in October, according to Tencent, the company which developed QQ.
And Fox’s Shadow might well have been one of them. “I log in on Friday nights, and Saturdays or Sundays when I feel bored. I usually spend about 10 hours chatting online every week,”she said. “But I rarely talk with strangers, especially boys or men.”
Even though she likes chatting, she is careful about making friends with strangers online. “You don’t know who you’re talking to. You should always be careful about who you trust online.”
