Dear Editor,

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

    The peacocks mostly (主要）live on the grassland of Dongfeng Square. Visitors can give them food freely. 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.

    I'm sure most of the visitors who throw food to the peacocks really like the birds, but they don't realize that they may be doing any harm.

    We should tell the visitors that what they have done is very harmful to the birds, and we also must stop this kind of thing from happening.

    Perhaps we can build some small shops beside Dongfeng Square to sell peacock food. For every one of us, it's our duty to give more love to these beautiful birds and to look after them carefully.

Yours,

Sun Yan
