Xiao Gao's Playground

A long, long time ago,
this place was a barren mountain,
without trees, without flowers,
not even a little bird would fly over to lay an egg.
 

Wouldn't such a mountain be too lonely?
So Xiao Gao's great-great-grandfather came,
and big and small trees from all over the world also came.
They wanted to work together
to turn this place into a playground...
