Hi Manfutu,
your recent changesets have created a lot of errors in the OSM database regarding duplicate nodes and self intersecting ways, for example here:

https://tools.geofabrik.de/osmi/?view=geometry&lon=106.50436&lat=38.55801&zoom=10&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=146466617

Can you please fix this?
Kind regards
Guido
