The man accidentally caught a big fish with its own "ransom" while fishing.

This was a surprising discovery, as the fish seemed to be sending him some kind of signal or threat, but he couldn't know exactly what it meant. However, after careful observation, the man finally discovered the true intentions of the big fish.

It turned out that the big fish was warning the man not to hurt it easily. When the man tried to approach the fish, it slapped its tail violently on the water to express its dissatisfaction and anger. At the same time, it kept swinging its body, as if to tell the man that if he didn't let go, it would bite his line.

After many attempts, the man finally understood the meaning of the fish and quickly released his hand. However, after releasing the fish, he felt a little regretful because he was afraid that he would cause harm to the fish.

So the man decided to try again, this time he didn't leave so quickly, but waited patiently for the fish to arrive. Soon, a big fish swam over, and this time, it didn't lose its temper with the man like last time. Instead, it just stayed by the side quietly, as if waiting for something.

In the end, the big fish was taken away by the man, but he gained a lot of inspiration from it. He believes that there is a delicate relationship between humans and nature, and if we can treat and respect them correctly, we can gain more understanding and respect. If we blindly destroy them, we will only get ourselves into trouble.
