Xing Liangliang, from Heilongjiang province, graduated from college last year. His parents, who live in countryside, only have traditional keypad phones. In early August, Xing brought his mother a smart phone. To better teach her how to use the smart phone, he decided to draw a user guide for his mother.

It took him more than half a day to finish the 14-page user guide. And his mother was surprised when she received this special gift. She didn't say much, but she read it carefully.

In these days, Xing and her mother had a tour in Harbin. Thanks to the user guide, his mother has begun to take pictures and search information with the smart phone.

After this user guide was uploaded to the Internet, many netizens said the guide is full of love for his mother.
