Old-timers jump on the mobile net bandwagon

Liu Li, 54, teaches third grade in Beijing and keeps touch with parents of her students via WeChat. Four years ago, she did not even own a smartphone. In 2012, her sister bought her an iPhone5 and a whole new world opened up to her.

"I found there were so many things that I needed to learn," she said.

Liu soon noticed that many of her co-workers were using WeChat, so she asked a colleague to install the app for her and teach her how to use it.
