OK, did you also understand that highway=private is very unusual?

Please add surface=* as well, as the meaning of surface:grade=0 is only clear when the surface is known.

Hi!
Please review: You changed a highway=living_street to highway=living street here. way/323692418
I suggest to use something like was:highway=living_street instead, as your tag looks like a simple typo.

Hmm, not sure what you changed but way/305486812
still has the same tags.

Hi!
I changed typo highway=Path to path here:
changeset/54091396

Hi and welcome to OSM!
I've noticed this changeset because of the unusual tags like highway=Hẻm 479
used here:
way/542690408
I assume that "Hẻm 479" is the name of the road and
In this case you should use name=Hẻm 479
The tag key highway gives the type of road, in this case probably highway=residential. See also highway=*
If you want to map access rules see access=*
but this is rather complicated for a beginner.
Please correct the data and continue.
Happy mapping!

Hi!
Please review way way/542829538
The tag highway=mini_roundabout is for nodes, not for circular ways.
The connected ways in the south have no tags.

What tags did you use? See
way/406674820/history
Was it wrong: I think yes, the tags are not useful for a way, but they may be correct for the node node/263203387
Feel free to fix it if you remember what it was, if not, maybe add a note that this junction needs survey.

Changed it to service now.

I meant this node
node/263203387
I am not a local, I just stumbled over the wrong tag on a way, Anyway, a traffic_light is not that important ;-)

Hi!
Why is the road still tagged as highway=4wd_only ?

OK, I've deleted the way. What about adding the tags to the shared node ?

OK. The 2nd one is not yet fixed.

Hi!
You added highway=traffc_signals to a way with railway=tram here. I assume you wanted to change only one node of this way?
way/390457206

Hi!
You created a very short way here with tagging that normally is used for a node. Was that intended?

Same here:way/492247885

Hi!
Please check highway=traffic_signals on
way/493464726
Did you mean track ?

Hi!
Please check your changes on way/284938446
I think you didn't want to add highway=traffic_signals to a building?

Yes, if you want to map the area maybe use area:highway , see
osm.wiki/Proposed_features/area:highway

Hi!
Please review highway=traffic_signals
here:way/516005124
I assume you meant highway=footway and maybe crossing=traffic_signals?
Please check also why the footways are not connected with the major roads. Are there bridges / tunnels?
