Most popular hiking apps (Gaia GPS, AllTrails etc.) support the standard used in China, do you think people just navigate with paper maps there?

AllTrails couldn't find "Shanghai", but my subscription lapsed years ago. Gaia is what I use on the ground but it's about where you are, not about where the trail is.....but I'm finding one of the ancient roads. A bit of a mess but it looks viable.

GPS works properly in China, it's just the maps are a lie. If someone made a .gpx of a trail someone else could use it. The line is pointy and a bit disjoint so I suspect someone uploaded points to Open Street Map.
