A recent survey by the University of Hong Kong found that more than 79 percent of Hong Kong people identified themselves as Hongkongers instead of Chinese. More identified themselves as "Asians" than as citizens of the People's Republic of China, AFP reported.
"Although 15 years have passed since Hong Kong returned to China, the mainland has not managed to win the hearts and minds of all Hongkongers due to differences in the political system and social customs," Chen Lijun, a professor at Sun Yat-Sen University, told the Global Times.
"Both the central and the regional government need to improve cooperation in dealing with issues such as mainland mothers-to-be giving birth in Hong Kong, and help people in the two areas better under each other's customs and conditions," Chen said.
