What is the setting of Gold Boy, Emerald Girl: Stories by Yiyun Li?

Each short story is set in some part of China. Kindness takes place mostly in a small community in Beijing. Some of the others take place in the provincial capitol, while still others take place in or around Shanghai. Some of the towns in which the stories are set are never mentioned by name, but the impression that they are small towns outside of the big cities is made clear to the reader.
