Why delete the `=service` road?

Why deleting `highway=` and `building=` + `addr:housenumber=` ?

There's no need to move both `highway=` roads and `building=`

Very obvious mistake of mistakenly attaching vertex. Don't delete details, and changing to simplistic shapes.

Why deleting the details, and changing it to right-angled corners?

N-th deleting `building=` without even changing to `building:part=`

Why are you touching `tunnel=yes` + `layer=-1`, and what does this do?

1. Roads passing through buildings common situation
2. You simply moved it outside the `landuse=residential` again to other side

The suggestion is to distinguish by `maxspeed:type=` `=sign` vs `=HK` (`=HK:urban` etc are wrong), not removing `maxspeed=`

Why are you moving the `building=` , but then delete the `=service` road?

Why are you deleting a unique `addr:housenumber=` ?

2. Buildings overhanging roads are common

Again deleting without even trying to change them to `building:part=`

Why are you deleting `building:part=` ?

There's nothing wrong here. Only not fully shared 1 vertex with `=park`

Please connect buildings attached together, not move them minusculely away. I have noted `apartments=terraced`

What are you trying to do here? Much deleting, and changed Hong Tin House shape by attaching vertex.

They are attached together in reality, and actually further overlaps vertically. There's nothing wrong with this in terms of standard OSM data layout either.

You don't even choose to change to `building:part=` for the `name=` (`building=` is used as they are recognized as different buildings, and each tower can have its `building:part=` which can't be grouped together in between )
