GUANGZHOU - More than 70 percent of the mentally ill in Guangzhou, capital of South China's Guangdong province, have not received regular treatment, local media reported on Thursday.

"The main problem is that most of the mentally ill and their family members feel ashamed and refuse to see doctors," Ning Yuping, president of Guangzhou hospital of mental diseases, told the Guangzhou Daily.

"The costly medical fee is another problem," she said.
