A terrapin does not mean poverty. It means that a person has never seen the world, and he is surprised and curious about what he has never seen, which arouses others' disgust and satirizes him as a "terrapin" and is very backward.

For example, a person lives in the mountains since childhood and knows nothing about the outside world. When he walked out of the mountains and came to a big city one day, he could not help shouting when he saw so many tall buildings and beautifully decorated hotels. Look here and touch there. It's novel. When others see his behavior, they will laugh at him as a terrapin, which is beyond one's cognitive range.

In fact, we should not laugh at anyone who is a terrapin. People always have a process of adaptation. We should help them and convey goodwill.
