What fable does swan shuttle fish and shrimp come from?

Moral of the story: Only through cooperation can we do things well.

If the partners are inconsistent, the cause will be bad; Although I have been worried, I still haven't made any progress.

One day, Parker, Shrimp and Swan went out to drag a car on the road, and the three guys shouldered the burden together. They push hard with their feet, and the veins stand out. No matter how they dragged, pulled and pushed, the car was still in place and did not move a yard. It's not that the car is too heavy to move, but there are other reasons: the swan is trying to lift it to the sky, the shrimp is dragging backwards step by step, and the pike is pulling to the pond again. I don't know which is right or wrong, and I don't want to delve into it; All I know is that the car is still parked in the old place.
