Last year my mother and I went to the HuaGuoShan Park.Suddenly the woman said:"He stole my purse!"The policeman saw that.Quickly ran."Wait!"Said the policeman.Then the thief ranning quickly too.My mother picked up the phone and quickly dialled 110."I want to report a theft.A man stole a purse from a tourist.He's in HuaGuoShan Park now.Please meet it on the other side of the river."A moment later.We saw some policeman standing round the thief.He was in handcuffs."Thank you!"said the woman."That all right."said my mother.In that day I was very happy.
