If someone tells you that "the tiger falls in Pingyang and is bullied by the dog", you can reply that "the dragon swims in shallow water to catch shrimp." The meaning of this sentence is that even the strong may be bullied by the weak in difficult times, reminding the other party not to look down on others and not to provoke others easily.

The response of this sentence is similar to the original sentence, which is a metaphor to express the truth that the weak can't bully the strong. At the same time, "dragon" and "tiger" are powerful symbols, while "shrimp" and "dog" are weak representatives, which meet the requirements of cleanliness.

I hope this answer can help you.
