Hi Lửng mật,
this changeset has created errors in the OSM database regarding overlapping ways (blue markers):

https://tools.geofabrik.de/osmi/?view=routing&lon=105.68432&lat=19.35871&zoom=11&baselayer=Geofabrik%20Standard&overlays=duplicated_edges

As you may know, this kind of error irritates routing software and looks ugly on the maps.

Can you please fix this?
Kind regards
Guido
