The great peng bird soars at a height of 9,000 miles.
Ha, ha. Look at that guy! What's he think he's doing wasting so much energy to fly so high?
My life is so easy. If I want to sing, I just buzz up to a branch.
If I want to eat a worm, I just flutter down to the ground. I couldn't more carefree.
There are differences between the realm of the sparrow and peng bird.
We shouldn't laught at the little sparrow in its small, self-contained world; nor should be envy the great peng bird in its grandeur.
