When I think of chatting with friends, I often ask what city life you want to go to in the future. Some people like bustling metropolis, and some people like places that can be easily reached by walking and cycling, which shows that different cities have different effects on people. A person’s happiness will be inextricably related to the place where she lives, This reminds me of a list called “the happiest cities”. I want to make illustrations about the relationship between cities and people according to the cities in this list.
