The well frog can't talk to people in the sea, but is confined to the air; Summer insects can't talk to ice or time; Qu's family can't talk to Taoists, but can only be tied to religion.
Frogs in the well can't talk to them about the sea because of their limited living space; Insects in summer are far from freezing to death, because they are limited by their survival time; It is impossible for people who sing in the countryside to talk to them about the avenue, because they are bound by education.

Brief introduction to the story
A frog lives in an abandoned well. One day, the frog met a chinemys reevesii from the sea by the well. The frog boasted to the tortoise, "Look, how happy I am to live here! Sometimes when I am happy, I will jump by the well for a while; Tired, I went back to the well and slept by the brick hole for a while. Look at those shrimps and tadpoles. No one can compare with me. Moreover, I am the owner of this well, and I am extremely free in this well. Why not come to the well to enjoy it often! " ?
The tortoise listened to the frog and told him about the sea. "Have you ever seen the sea?" ? The vastness of the sea stops at a thousand miles; The ocean is over 1000 feet deep. There were nine floods in ancient ten years, and the water in the sea didn't rise much; After eight years and seven years of drought, the water in the sea was not so shallow. Living in such a sea is really happy! The frog in the well listened to the tortoise and stayed there in surprise. There is nothing more to say.
