Laosicheng Site in Hunan province

The Yongshun old Tusi city, or Laosicheng Site, in Central Hunan province has a history dating back more than 600 years. Lying on the bank of a river, it is the largest, oldest and best preserved Tusi city site in China, with a temple, ancestral house, cemeteries and memorial archway. The complicated sewer ditch network is still working.
