You may find it easy and fun to use smartphones.But for many old people，it's a hard thing.Liu Siyuan from Beijing 101 Middle School sees the problem.So he tries to teach the old how to use smartphones with a guidebook（指南）.
   The 16-year-old sets up（建立）a volunteer（志愿者）group called SilverHair.Its seven students spend around half a year writing a 300-page book called May I Show You How to Use Smartphones.
   The group interviews more than 1，000 old people and talks with many in old people's home.They find out what the old people care most about with smartphones. "How to use WeChat" is very important today，so this becomes one chapter（章節(jié)）of the book.The other nine chapters include online shopping，using online maps and more. "The old people can look up the book any time they need，just like using a dictionary，"says Liu.
   The group prints（打印）out 500 books and gives them to the old people.They'll soon write the second book.It will have more useful things such as "how to use GPS" and "how to use Meitu".
