Shaanxi is one of the cradles of the Chinese civilization. Fossil remains of Lantian Man (body of about 5, 00,000 to 600,000 years ago) were discovered here. Spread across a dozen or so kilometers east of Xi’an are Banpo remains of the matriarchal society. There is a great wealth of history relics of the Zhou, Qin and the following dynasties. At the time of second civil revolutionary war, a revolutionary base area was set up in Northern Shaaxi with Yan’an as the center. From 1937 to 1947, Yna’an was the seat of the Central Committee of the Communist Party of China.
