Afaik there are more than two clinics in this building; can you confirm? Or if this changeset is an unfinished draft with more to be added later then never mind.

Is there really a viewpoint here?

Still, I don't think you should upload meaningless (to others) changesets for your own convenience like changeset/170574528 .

It is not that difficult to draw three straight lines in JOSM.

That changeset was created on 2018-06-17. Looking at the latest imagery available at the time (https://livingatlas.arcgis.com/wayback/#mapCenter=114.22278%2C22.30561%2C19&mode=explore&active=8255), there is indeed a yellowish stain here.
Given that the user who created it (PicaPico) has a history of mechanically drawing features (see e.g. changeset/158480422 changeset/158568447 changeset/158520199 ), it is likely that they/their machine thought the stain was a wetland.

I don't know if you noticed, but their objects are inevitably deleted and redone every time you calibrate/beautify path shapes. changeset/160714875 changeset/173934317https://www.openstreetmap.org/changeset/173933922

What is the purpose of this changeset?

To add to this situation, the user who created the wetland has a history of low-quality edits, sometimes with AI which does a poor job of identifying features, e.g. mistaking cars for buildings.

`open:conditional=` looks like it should be `opening_hours=` instead.

It seems like there is only one clinic in this building, which should mean that a clinic node is unnecessary?

Sorry if my previous comment was not clear, I meant is the `name=` change really necessary, if the other variant is already document in `alt_name=`? How do you know which one is more correct? Are you sure if "薄刀屻" is wrong when I can find so many uses on the internet?

Isn't there already `alt_name=`?

Really `width=784`?

Then, sounds like it should be `barrier=fence` or `=wall`.

Hi there, what is way/1318182599 ? Does it actually exist? I can't see anything buildings on aerial imagery.

1. Please don't trolltag (osm.wiki/Trolltag). Use `proposed:building=*`.
2. "Proposed Campus Extension of The Hong Kong University of Science and Technology at Clear Water Bay" is a `description=`, not a `name=`.

Please don't trolltag (osm.wiki/Trolltag). Use `proposed:building=*`.

I have reverted this changeset in changeset/176289492 for the following reasons:

1. You have a history of messing with osm data in an attempt to fix a problem with your router.
2. Misunderstanding on how routers work; they don't always update instantly.
3. Please don't delete ways with 10+ versions of history and redraw it.
4. Geometry is worsened after redrawing.
5. Tunnel snapped with unrelated building.
6. Changed `layer=` from -1 to -7 for no apparent reason.
7. `name:en` removed for no apparent reason.
8. I am pretty sure the official name is 中九龍幹線, not 中九龍幹綫.

See changeset/176289291

1. Vehicles from Kai Fuk Road westbound can not go to Shing Kai Road, so it should be kept as `=motorway_link`.
2. The extent of tunnel area is already conveyed with `motorroad=`.

Why is it a `=trunk_link`?

I quote level=*#Multiple_values

> Use a hyphen (-) to specify a range of numbers with no missing values. E.g. the elevator of a 32-storey high-rise with two basement levels will be tagged `level=-2-32`.

Hi there, would `note=level: 2 through 6` be better represented as `level=2-6`?
