Once that file is in place, when you choose :"Settings" >> "Configure Map" >> "Map Source" >> "Install more", then scroll about 1/3 of the way down the list to the section on China maps (its not alphabetically listed) where you can select which ones to ad to your regular "Map Source" list.

I added Baidu, Sogou and GoogleMaps of China. The only downside to using these alternate maps is that they are not offline maps like the regular OsmAnd OpenStreetMap map. But, as long as you enable a data connection on your phone, you can use these maps. When I have a section of map on my display, I just switch to a different map source and it shows the same area but with the new map. This is great for filling in the gaps where OpenStreetMaps is missing some smaller roads.

It even uses google map, with corrected offset and with just a normal internet connection (no VPN)!
Once you displayed a section of map, the corresponding image tiles of that section are cached to the "tiles" folder, then next time you can display it off-line without data connection. Even you can download multiple tiles with multiple zoom scales at one time through "Download map" item in context menu.
