The whole song is:

1 Can write like a pencil, swim in the water like a duck, listen like an ear, float in the wind like a red flag, catch fish like a hook, whistle, mow the grass like a sickle, circle up and down like a gourd, and serve rice like a spoon.

There are also different versions:

1 Like a pencil, it can write. Swimming in the water like a duck. 3 like ears and listen to sounds. Like a flag, floating in the wind. 5 like a scale hook, to buy food. Like a whistle, blowing sound. Cut the grass like a sickle. 8 is like a twist, twist together. Like a tadpole, its tail wags. 10 is like a pencil and an egg.

This ballad is one of the kindergarten textbooks, which is used to teach children to learn basic numbers. I've been talking for more than ten years.
