The historic courtyard home of Prince Gong's (aka Prince Kung) mansion is one of Běijīng’s largest private residential compounds. It remains one of the capital’s more attractive retreats, decorated with rockeries, plants, pools, pavilions and elaborately carved gateways, although it can get very crowded with tour groups. It's reputed to be the model for Chinese writer Cáo Xuěqín’s 18th-century classic Dream of the Red Mansions.
