All of the solutions seem to be -very- complicated compared to simply using https://wambachers-osm.website/boundaries/ answered 19 Feb '20, 09:32 SimonPoole ♦ Hi,Simon:

Hi,augustind: it's really a problem for me to use the website ; the export button can not work at all. so follow your advice : download your data from http://download.geofabrik.de/asia/china.html directly in shapefile and filter it later (but the shapefile is really big for China). year ,it's really a big file to import to QGIS tool. this file contains so many lines or builds polygeon... so if i just only want to filter all the area ,how do i do? it means i only want to filter the level of boudary like changed the : ["admin_level"="4"] to ["admin_level"="6"] or ["admin_level"="8"] how do i do ? Thanks

Hi, You could test with http://overpass-turbo.eu/, using wizard tool to build your request. For instance, for your first point "1.Get the whole china country boundary with province level (a whole country boudary line and province lines)", you could use these expressions for wizard:
You may have to increase default timeout (25). You can try QuickOSM in QGIS to get it in shapefile, or import your overpass json result in QGIS to convert it. You can also try to download your data from http://download.geofabrik.de/asia/china.html directly in shapefile and filter it later (but the shapefile is really big for China). To know which admin_level to use to request data, have a look at Wiki OSM - Tag:boundary=administrative (see China entry in the table) Good luck !

emm; but i need detail code like this to run in wizard tool(but it always failed to run ):
So maybe i need a code that really come to run successfully ; thanks
