In this project, I want to explore how the relationship between people affects people’s behavior. I will meet people I know in the community, but most of them are relatives and friends of my parents, but I do not share with them I’m not familiar with it, but because of the relationship between us, I often have to talk a lot. When I meet my elders and friends in China, I want to say hello, but in this case, this kind of greeting has no practical meaning. We greet each other because of the relationship between us
