It is the center of Chinese civilization and East Asian civilization and enjoys the reputation of "the cradle of the Chinese nation". It is not only the birthplace of the Chinese nation, but also one of the important human origins and prehistoric cultural centers in Asia. Founded by Zhou Wenwang, it was built in12nd century BC and has an uninterrupted urban development history of 3 100 years. There were 2/kloc-0 dynasties and political powers, including Zhou, Qin, Han and Tang, which established their capitals here. It was the ancient capital of 13 dynasty (17 dynasty) and the political and economic capital of China. 198 1 year, UNESCO identified Xi' an as a "world historic city".
Xi 'an, also known as Xijing, Xi Du, Fengcheng and Doucheng, is called "pickaxe" for short. From ancient times to modern times, they used the names Tanjing, Haojing, Tang Ao, Xianyang, Chang 'an, Chang 'an, Jingzhao, Daxing, Yongxing, Fengyuan and Xijing, among which "Chang 'an" is the most common and famous.
Xi 'an, with 2/kloc-0 dynasties and political power as its capital, is the capital with the most dynasties, the longest capital and the greatest influence in the history of China. (yanliang district in Xi 'an is also the famous ancient capital of China-Liyang) Among these dynasties, the Han Dynasty and the Tang Dynasty, which used Chang 'an as their capital, were the most prosperous periods in China's history, when Chang 'an was an international metropolis. Chang 'an was the largest city in the world from BC 195 to AD 25, and from AD 637 to AD 904. At the peak of its development, Chang 'an has a population of over one million, making it the first city in human history to reach one million. Weiyang Palace in Chang 'an in Han Dynasty and Daming Palace in Chang 'an in Tang Dynasty were the most influential and magnificent palaces in the world at that time, and Daming Palace in Tang Dynasty was also the largest and most magnificent palace in ancient China, with an area of 4.5 times that of the Forbidden City in Ming and Qing Dynasties. Later, other metropolises in the world did not reach or surpass the height that Chang 'an once reached, and this fact remained until the15th century (the position of the first urban area remained until modern times). Chang 'an has always been the center of the world in its heyday, attracting a large number of foreign envoys and worshippers.
