What is the background music of the poem "I am with you" recited by Li Jiaming and Fang Qiong in the 20 10 New Year Poetry Club?

Butterflies are small and light.

Very small, with flowers.

Big, heavy has become the favorite of spring.

The grass is small and light.

A grain of dust is very small, very light and insignificant.

With my father who planted rice seedlings in the field.

It is big and heavy, which has become my favorite.

A drop of water is small, light and insignificant.

Plus my mother washing clothes by the river.

It doesn't matter if you are older or heavier.

My favorite. First, I am small.

Light, insignificant

Add it with you.

Favorite for several years

It's just that addition is too simple.
