Chinese-American photographer Wing Young Huie is chasing both sides of his identity, first touring the US and most recently Guangzhou, where he talks to Xu Jingxi.

Sitting on the stairs in front of the post office next to Guangzhou Railway Station, 47-year-old migrant worker Cheng Jiping vacantly stares at the bustling square in front. He has been hungry all day.

"I heard that there are many clothing wholesale markets near the train station and I thought it would be easy to find an odd job, like a porter. But I failed," says Cheng, who is unable to rent a room and has slept in the open for several nights.
