Now there is this story in the first volume of the second grade of primary school Chinese in the textbook of Beijing Normal University, which appears in the form of poetry and is called "swan, prawn and barracuda" by krylov.

If the partners don't unite,

Can't do anything well,

It's no use making noise,

In the end, I can only ask for trouble.

Once, swans, prawns and barracuda,

Trying to tow a cart,

They were all built by themselves,

Pull and pull hard,

The cart stopped moving,

Although the car is not heavy,

But the swan stuck its neck out into the clouds,

The prawns hunched their backs and leaned back hard.

Barracuda is bent on jumping into the water.

It's none of our business who is right or wrong.

All I know is that the cart is still there.

Never touched a penny.
