Every grass is trying to grow towards the sky. What song does this word come from?

The lyrics are as follows:

I see the sky is clear, and there is a light.

Seagulls on the blue ocean, flying freely;

Every ship has a direction;

Happy sailing, happy distance;

I see the earth in full bloom, green hope;

Sunflowers smile and stare at the sun;

Every grass is trying to grow;

Stick to the sky.
