What's the story behind your 'China Select Provincial Expressways' system you want to introduce today? Shouldn't we have one system per province like you already have in place for two provinces?
Edit: chns -> chnsf

There were major changes in 2017 and 2022 that downloaded many freeways from national level to provincial level, and the ones added to chns were just the ones that already in chng in various parts of the country that were previously in chng, rather than leaving them in unprocessed wpts, given that there is already a substantial list of them already. They can be parked there for when we are ready to take a stab at those.
We've reviewed 0.5% of chng and chn**s--there's 180,000km of freeways in China, so chns makes these stragglers a little more documented. Basically usansf with Chinese characteristics.

What happened to the system?
It's still in systems.csv (https://github.com/TravelMapping/HighwayData/blob/master/systems.csv#L437C10-L437C45) but missing in HB (https://travelmapping.net/hb/).

I guess I know why. I just run data check with the currently merged PRs:
1: [Errno 2] No such file or directory: '/HighwayData/data/CHN-HA/chns/chnha.s59.wpt'.
Edit: Fixed with https://github.com/TravelMapping/HighwayData/pull/8370

The system should be renamed to chnsf (Select Freeways). I know that those routes are called "Expressways" (thus, chnse might be the way to go) but our select system do simply refer to the road standard. Freeways. For instance, German Select Freeways are called like that, system code deusf. Not deusa (Select Autobahn). neroute2 also applied this for myssf and thasf.

Renamed.
