Zhang Ming, a college graduate from Shandong, created a 9-page＂WeChat guide＂(微信指南) to parents. With drawings and simple words, the step-by-step guide explains how to send messages, take pictures and make video calls. ＂My parents are getting old. They need an easy way to learn how to use technology,＂Zhang said.

Zhang’s experience is common nowadays. In the world, 40% of parents learn about new technology, including computers, mobile, Internet and social media(社交媒体), from their children, according to a survey from the International Communication Association. Parents teach their kids almost everything when they are young. Now for the first time, the teachers become the students and the students become the teachers.

The change of roles comes from the rapid development of society and technology, according to Zhou Xiaohong, a professor from Nanjing University. Zhou said the Internet and other forms of media give children more ways to get information. So, it’s possible that children know more than their parents do these days.

According to the China Internet Network Information Center, in China, 56. 7% of Internet users and 67.2% of social media users are under the age of 30. Young people usually act as a link between their family and the new environment. But when they teach their parents new technologies, parents can connect to the new world by themselves.

In Zhang Ming’s eyes, teaching his parents about WeChat brings him closer to his parents. ＂People can communicate more by using new technology. Why should we keep our parents out?＂said Zhang.
