Longzhou Museum
in the square across from the new bus station
While Longzhou is now a sleepy town it has had quite a history. The Longzhou museum has many artifacts and paintings from the Longzhou Rebellion, which was led by Deng Xiaoping. Some of the staff speak English and may be your best bet for tourist information. A Chinese language leaflet available here includes a tiny map - infuriatingly difficult to use but there does not appear to be any other maps available.
