I've undone this changeset entirely, because the object was clearly added in the wrong place.

I've undone this changeset entirely because:
• The changeset introduced a number of errors.
• The address provided (Century House, 3–4 Hanoi Road) contradicts the address shown on the linked website (Hart House, 12–14 Hart Avenue), so out of caution I have also removed the store in addition to reverting the errors.
• The added node did not specify the actual function of the store. The tags "shop=hookah" and "amenity=hookah_lounge" may be appropriate (see shop=hookah, amenity=hookah_lounge).

I've modified the tags on the object. Let me know if you think I've made a mistake.

Hi, unfortunately this already existed in the map before you added it (way/264462780), so I'll remove it.

Done. (changeset/67740659)

As suggested by the wiki (railway=station), I'll add landuse=railway and see if it works.

This changeset caused the stations to stop rendering.

Of course, this is not to say that I actually know whether aaronsta plagiarized in this series of edits, but considering that government maps of Hong Kong are copyrighted and the lack of appropriate sourcing (source=aaronsta on changesets), I would have some doubts.

Is there a reason highway areas would be altogether inappropriate? They are quite frequently used (https://taginfo.openstreetmap.org/keys/?key=area%3Ahighway).

Separately, the user who made these changes was blocked at least once for making illegal imports, which I suspect might be a problem here (though the additions were years ago).

Sorry, I didn't realize there was also a layer conflict with the Cross-Harbour Tunnel (the ways weren't downloaded by the JOSM reverter, so the validator couldn't have caught it). I thought the only conflict was with the Tsuen Wan Line.

Does the slip road actually have a name? I'm fairly sure it doesn't, but I'm not sure. (Also, the Chinese name should be before the English name.)

The edit to the bus-only slip road was partially reverted by Kovosch. changeset/67581939

I've partially reverted this changeset for several bus routes, as their members were incorrectly changed to begin at Yuen Long (West).

Partially reverted to restore railway=station for 96th Street subway station (Second Avenue Line).

I'm not sure if my reservation about the primary_link classifications is just because they (i.e. 255891700 and 236039696) would look strange crossing through service roads, although it would probably be the logical way to label them if the overpass (33277266) is tagged as primary_link.

I'm not sure. I think primary_link might be appropriate for it and way/225114285, but it might depend on the classification of the other ways between Tai Po Road and the racecourse.

These ways should probably also be motorway_link, since they are one-way and only connect to another motorway_link at one end:
• way/135619198 – service (2018-11), was previously motorway_link (2017-10) and residential (2011-11)
• way/135716499 – as above
• way/255891627 – service (2018-11), was previously motorway_link (2017-10) and service (2014-01)
• way/44488054 – service (2018-11), was previously motorway_link (2015-03), trunk (2015-03), motorway_link (2011-01) and trunk_link (2009-11)
• way/44488132 – as above
• way/644703033 – service (2018-11); was split from way/209216309 – motorway_link (2013-03)

Some of these ways could be primary_link for similar reasons:
• way/225114285 – service (2013-06)
• way/255891700 – service (2014-01)
• way/135716488 – service (2011-11)
• way/294630970 – service (2017-10), was residential (2014-07)

I'm not sure about all of these. All of the 2017 edits were by bgard and all of the 2018 edits were by 🗺🗺🗺.

On discussion fora: I agree Telegram might be useful, or Discord. Wikimedia (English) and OSM (English) each have Discord channels. Wikimedia Hong Kong (Chinese/English) has a Telegram group.

@Kovosch I don't think so, although it would be very nice to get one started. I've been here for almost six years and haven't been informed of one, and the wiki page (osm.wiki/WikiProject_Hong_Kong) doesn't link to any external groups or forums.

Why would it be appropriate to keep 562205337 as a residential road?

@GeoidDude I agree with you for all five ways, although I'm somewhat unsure about the service classification. Some of the other slip roads (e.g. way/135716499, way/255891627) also seem to have similar issues. It's worth noting that a lot of these link roads seem to originally have been classified as they currently are until changed by bgard (also from Apple) in 2017.

I think primary_link would be appropriate. My Mapillary photos (https://www.mapillary.com/map/im/I3XhvAsr3a_zzi3i0xi-Pw) indicate that on the southbound on-ramp the "start of expressway" sign is very close to the junction with Tolo Highway, and the three ways modified in this changeset are quite far away from the junction and do not have to lead onto the highway anyway. The bridge on the other side of the interchange is possibly incorrectly tagged as residential; should that road also be tagged as a primary_link?

(I don't think the location of the posted signage is completely relevant, since the tagging convention doesn't define the use of link road tags based on the legal classifications of the link roads themselves, but on the legal classifications or importance of the non-link roads. The UK also has such signs at motorway on-ramps, but the ramp isn't split at the exact location of the sign, which was what 🗺🗺🗺 was doing.)
