Hi, osm-sputnik. Thanks for your prompt reply. Yes, you are correct; it is a telescope, not a building. The current issue is that it cannot be retrieved using the nominatim API. You can try this search link: https://nominatim.openstreetmap.org/ui/search.html?q=Five+Hundred+Meter+Aperture+Spherical+Telescope

I am not familiar with OpenStreetMap, and do not know how to retrieve it now. Last month, it was okay. Could you tell me how to retrieve it? The Python package OSMnx relies on the Nominatim API, so it does not return this feature now. My program is based on OSMnx, and it uses the result to download the satellite image.  FAST telescope is a very good example.
