Do you have the China maps available that are subdivided at the prefecture level for 1995? I have seen the county level ones on your website but these are too detailed for my purposes.
The maps we have available represents the status of China as of 31 December and 1 July 1990. The dataset shows boundaries of China at the provincial and county level. However, if you have a list of prefectures and a GIS software, you may be able to combine the different counties to form the prefectures, or you can also use the GB codes to identify the different prefectures, please see
