高手帮我改下短文

Once upon a time，we are living in a fantasy land.We can hear bird sing in the early morning, the water breath slowly; we can reach every corner, and feel the pulse heavily;we laugh heartedly because of the dream and happiness.We love every person around us, there is no war, no exploitation .We are brave, united, and free.It is just like a nursery rhyme , or as beautiful as a poem .We are born, eventually and maturely we are old.
When would this world will come back again?
