You can find basic information about provincial boundary changes on my "Statoids" site at http://www.statoids.com/ucn.html. The only major changes since 1980: the formation of Hainan province and Chongqing municipality, and the annexation of Hong Kong and Macau. I'll see if I can find anything about the Qinghai-Gansu border. -- Gwillim Law ----- Original Message ----- From: "Paul Eggert" <eggert@CS.UCLA.EDU>

Which provincial boundaries have moved since 1980? This knowledge would help me in my task. For example, <http://en.wikipedia.org/wiki/Image:China_administrative.png> says that the Qinghai-Gansu border has moved but gives no details.
