Maples in the Mist: Children’s Poems from the Tang Dynasty is a lovely way to introduce children to the poetry of China. Each page holds a poem, a dreamy illustration, and Chinese characters. A section at the back of the book tells a bit about each of the poets. 
Little Pine
My little pine tree is just a few feet tall.
It doesn’t even have a trunk yet.
I keep measuring myself against it
But the more I watch it, the slower it grows.
~Wang Jian
