Sites of three ancient cities, dating back to different dynasties, were discovered by a team at an archaeological site at the ancient city of Liyang, said Liu Rui, a researcher of the team.
Liyang, a former capital in the Qin and Han dynasties, is now located at Yanliang district of Xi'an, capital of Shaanxi Province.
Three baths and a fireplace have been excavated at one site. The baths have been built with beautiful tiles and bricks, with sewage outflows, the state-run Xinhua news agency reported.
The 2013 excavation of ancient Liyang was conducted by the Chinese Academy of Social Sciences Institute of Archaeology and the city's cultural relics protection and archaeology institute.
