Swan barracuda and shrimp tell us that when choosing partners, we should choose partners with the same aspirations and goals, so as to achieve effective cooperation and promote the success of things. This is a Russian fable by Ivan andreyevich krylov.

Once upon a time, there was a place where there were swans, barracuda and shrimp. They were good friends. One day, they quarreled. Its teacher asked each student to pull a car up the mountain, and the three of them happened to be a group. Swan pulled up desperately, pike pulled forward desperately, shrimp pulled back desperately, but the car didn't move at all.
