Dear editor (编辑) ,

     I live in a beautiful city.  Many visitors come to my city. There are so many colorful peacocks

(孔雀)   here.

     The peacocks mostly live on the grass land of Dongfeng Square. They are given food freely by

visitors. They usually throw food to them, and don't think about at all whether the food is right or not.

Some of the peacocks became ill, some even died after eating the bad food given by the visitors.

     I'm sure most of the visitors who throw food to the peacocks really like the birds, but don't realize

that  they may be doing them harm.

     The visitors should be told that what they have done is very harmful to th'e birds, and this kind of

thing must be stopped from happening.

     Perhaps we can build some small shops beside Dongfeng Square to sell peacock food. For us

every person, it is our duty to give more love to these beautiful birds and to look after them carefully.

                                                                                                                                        Yours,

                                                                                                                                        Sun Yan
