What does this achieve?

Please don't add descriptor labels to `name=`, only in `description:zh=`.

Please check that they are referring to different things. This is a event area inside the stadium. You can simply remove the names if you find this "not allowed".

And don't abuse `=path` when it's simply `=footway`.

Please don't use `highway=*` + `construction=yes` in place of `highway=construction`.

Yes you can have it! Lots of buildings.

But Choi Hung Rd goes between NW and SE here. It's like Hammer Hill Rd terminates here, or forks out. It's not merely a left turn or right turn. Rather it's continuing on the same road.

Please don't upload test changesets, which duplicates osm.org/way/40664120

This is not the correct solution. An "inaccessible" feature still exists. You should add a `barrier=gate` as the physical obstruction, and `access=private` for the legal rule.
In the process you deleted the intersection for the opposing roads together.

Hi, the problem here is the "archaeological site" extends to the fenced area. Is there any better solution for the stone circle itself?

According to foreign experience, this should be allowed. The illegality should be represented otherwise.

`=parking` is the entire parking lot including planters and any structures, not the same as `=parking_space` + `capacity=`.

It doesn't make sense for Peel Rise and public roads connecting driveways to have the same classification as Mt Kellet Rd. At minimal, you would use `=unclassified`.

`=tertiary` and `=residential` are based on its importance, not where it is.

2 is needed for double parking, allowing vehicles to stop outside of special parking bays, or allow stopping in a parking bay on the side of a `=fire_lane`.

I need to indicate:
1. A stopping restriction area across different lanes (this situation)
2. An additional stopping restriction outside of parking bays to control the parking bay and lanes separately

There's nothing named "Hong Kong Metro" though?

This looks like a copy & paste mistake. Simply remove the names. There are a few structures here.

`=pedestrian` means a pedestrianized vehicular street, not any road for pedestrian. You are looking for `=footway`, plus `footway=sidewalk`.

Please don't add route names to roads. They should be kept separate when there is a street name.
