Comment On A Very Old Man with Enormous Wings

This is a typical way to start a story. First there is an isolated society in which everyone lives contently and peacefully. And then something or somebody bursts in and throws a stone into a calm lake. The essence and the meaning that the author wants to present in the story will be revealed in people’s reaction and the consequence that the intruder brings. In fact many novels are set this way. I believe there must be a certain term for this way of plot setting, which is more professional.
The old man in the story must be representing something. Maybe he was sent there to test those people(and they obviously failed). People rarely showed mercy to him. This is not strange, if we ask ourselves this question: What would we do if we saw a very old man who looked just like someone’s grandfather fall on the ground? We probably would help him stand up and ask him what was going on. The same thing is very likely to happen in the village mentioned in the story. It is a normal old man(without giant wings) who needs help. People will think that he is one of us human beings so we should give him a hand. But the old man in this story is with has wings! Weird enough. He was not admitted accepted by mankind. And they had no idea where he came from and who he really was. They are cruelly curious and maliciously interested. When faced with something they have no knowledge of, people tend not to believe and show kindness, but instead are suspicious and want to get rid of the thing so that it cannot disturb their former life. In the drama Heshibi, written by Zhang Xiaofeng, a famous Taiwanese dramatist and writer, the same story has been told. People are reluctant to admit to the existence of something  novel so unusual, which will probably conflict with their original belief and goes beyond their knowledge. They never want to sit down and seriously learn about it, but instead mocking mock it and when a new one comes up they just transfer their attention.
