The beauty of birds

The beauty of birds, is like a sunshine;
Flying at the sky,with a freedom;
Gives us a enjoyment,
Sometimes sit, sometimes fly and spend the whole day and night at sky
And trees;
They belong to neither rich nor poor;
Doesn't have jealous, Doesn't have proudy, and anxiety;
Whether have a full of enjoy and freedom;
The way they fly, the way they sing ,
Sometimes cool our mind, and thoughts.
