Be  Careful !

           I  have  been  to  calgary for a  month ,and I really like this city; people look friendly and lovely; They always  smile and  be enthusiastic  in helping  others. The   time I touch with this city is short , so I didn’t contact any kinds of crime.in china, there are some crime about fraud. For examples , some criminals pretending to be  a police   call some elderly people at home , and tell them  that their  bank card  has  some problems , they need to modify bank card password . some elderly people  trust them, and tell the criminal  bank card and password; qickly, the criminal copy the card and steal the money . the elderly people even don’t know that they are  defrauded. Sometimes ,it’s too  late to alarm to the police,and the police can’t timely access to useful  information. Fortunately, more and more elderly people know this fraud and will not believe this.It is necessary to be careful and don't believe other people easily!
