It is 8:30 at night. A group of young workers are busying processing products at a plant in Zhuhai city, South China’s Guangdong province. They have been working for nearly 10 hours. All of them are born in the late 90s and come from rural areas outside the province. Wearing blue uniforms and having peculiar hairstyles, they make a living by repeatedly working on the assembly lines and contributing as one of the forces of the city’s construction.
