This study attempted to investigate Hong Kong junior secondary students' conceptions of China before and after the 1997 handover of Hong Kong to China, with a view to finding out any changes in their conceptions, and if any, the factors that might have contributed to these changes. The study found that, over the years from 1997 to 2009, students still viewed China as backward in many aspects, and still held superficial, fragmentary and even contradictory and inaccurate conceptions of China, but their conceptions were getting more positive and deeper in 2009 than 12 years ago. This paper maintains that students' greater exposure to China's development in various aspects through various information sources played a prominent role in shaping their conceptions of China. The implications for learning and teaching are discussed.[Copyright of International Research in Geographical and Environmental Education is the property of Routledge.
