"Big cities and small cities are like two worlds. Basically, young people don't want to stay in small places, but the resources of big cities are far from enough. It means some young people can only leave when they can endure no more. Many young people are well-dressed and have a good life. They don't think about getting married, going home or the future," Lin said.

"By the time they have to think about the rest of their lives, they will find time is running out and they still have nothing. Maybe one day in the future, there will be a huge wave of sad emotions in the big city. It is not because of awakening, but because of vain dreaming. "

The exhibition will run through Dec 8.
