I'm sure most of the visitors who throw food to the peacocks really like the bird, but they don't realize that they may be doing them harm . Visitors should be told that what they have done is harmful to the birds, and this kind of thing must be stopped. Perhaps we can build some small shops beside Dongfeng Square to sell peacock food.
