Capital city of the Agatean Empire, which rules the whole of the Counterweight continent. Hunghung is a busy and crowded city with even more market stalls than Ankh-Morpork. It once seemed to a traveller (Rincewind) that life in Hunghung takes place on the streets. There were so many people that it was hard to actually see the road surface.
The place is actually controlled by eunuchs.
The Forbidden City of Hunghung is the part of the city that is the Emperor's palace.
