Hi, this import is of bad quality as the ways are often not connected to each other. See https://tools.geofabrik.de/osmi/?view=routing&lon=107.31982&lat=57.05298&zoom=8&baselayer=Geofabrik%20Standard&overlays=unconnected_open_ends_1

According to your import page you announced that the JOSM validator rules would be solved manually, which obviously wasn't the case. Please fix theses issues manually.

thank you
