Yang Xiaoxia doesn't belong to that amazing beauty, but she looks good when dressed up. She was born in a small county in a northern city at the beginning of the 1990s. In fact, she is very ordinary. Like most people of our generation, she came to the big city through cruel examinations; Like most of us, we go to school, fall in love, find a job, experience emotional exchanges, the ups and downs of the workplace, and the joys and sorrows of life over the years, Yang Xiaoxia has passed by all kinds of people. They are like one after another waves, jumping, galloping, and finally disappearing into the vast torrent of life. We mark them with twelve constellations. Together with Yang Xiaoxia, they constitute a small group image of this era.
