Many volunteers have helped old people learn to use smart phones.However，old people still have trouble using them.It takes much time and effort，and more importantly，old people can easily forget what 'they've learned and the volunteers have to do the same job again and again.
   Liu Siyuan from Beijing 101 Middle School noticed the problems and tried to solve them with a guide book.The 16-year-old set up a volunteer group called SilverHair.Its seven members spent about half a year writing a 300-page book called May I Show You How to use Smart Phones.
   The group members made a survey of more than 1，000 old people and talked with many in nursing homes （养老院）and found out what the old people care about with smart phones. "How to use WeChat" was on the top of the list as this app covers many parts of life such as chatting，money transfers （转账）and health code （健康码）checking.These make up one chapter （章节）of the book.The other nine chapters include the basic functions （功能） of phones，online shopping，using online maps and more.To make the book easier for older readers，Liu also made the pages light yellow and the words big.
   "Many old people preferred not to use smart phones at first，but the guide book helped，us make them more willing to learn， " said Liu. "And they can read the book any time they need，just like using a dictionary."
   The SilverHair members have printed out 500 copies with their own money and handed them all out for free.They will soon start working on the second edition （版本） which includes more guidance such as hospital registration （挂号） and photo editing （编辑）.They also hope for support from the public so they can print more copies and help more people.
