"It is becoming impossible to find people to work," said Han Zhongliang, a 46-year-old factory boss from Hubei. "I have been here ten years and I used to have 30 to 40 employees. But this year I will be lucky to find 20 who can do the job are willing to work for the wage we offer: 5,000 yuan (£490) a month. If things keep on like this, there won't be any labour at all in South China in five years time. Since the Olympics, it has just been worse and worse for our business."
