What are the fables about turtles drinking water?

Turtle drinks water: When the turtle swims in the river, he sees that the water in the river is clear and wants to have a taste. But there is a poisonous snake by the river, staring at the tortoise. In order to avoid being bitten by snakes, turtles have to swim around constantly, and they dare not go ashore to eat grass when they are hungry. Finally, the tortoise was so hungry that he had to go ashore and was killed by a poisonous snake. Moral: This fable tells us that we should always be vigilant, know how to weigh the pros and cons, and don't be greedy for temporary enjoyment and ignore the existence of danger. Otherwise, you may pay an irreparable price.
