When you 'discover' a city that is not on OSM

But that is not a city in terms of the meaning of place=city in OSM.
In general having settlements of this size not mapped beyond a node is nothing rare in OSM. It was not rare in Europe 5-7 years back either.

An active Chinese mapper, what a wonder! :)
On a serious note, It can be that some mappers are not good at detecting roads-vs-paths in Chinese mountains using imagery, especially if this locality has no other sources.

And even where we have a place-tag don’t forget that we have still tons of unmapped places: http://resultmaps.neis-one.org/unmapped#2/23.7/3.5
