Recently, someone in the Malagis GIS group was looking for historical maps of Chinese dynasties. While a friend from Qingdao shared some high-resolution scanned maps, I remembered seeing an online historical map service maintained by an institute in Taiwan. After asking GPT, I found it again. If you're interested in historical geography, this is a valuable resource.
