2 years ago We will investigate your issue asap, but we recommend that you do not add "市" or "县" to your query, generally, changes in local administrative divisions around the world may not be sync with every government official data in time, so it is impossible to keep our database up-to-date.
Xunyang has changed to a county-level city since August 2021. "location=旬阳市&adm=陕西省" gets no result, but parameter location=旬阳县 gets right.
