Xi 'an, known as Chang 'an in ancient times, is the first ancient capital of China and one of the four ancient civilizations in the world. It was built in16th century BC. Xi was once called Daxing City, Jingzhao, Fengyuan and Xijing. Xi 'an is the capital of Shaanxi Province, People's Republic of China (PRC), one of the sub-provincial cities of China 15, one of the seven regional central cities in China, the industrial and commercial center in northwest China, and one of the largest central cities in China section of the New Eurasian Continental Bridge. One of the national health cities. World famous historical and cultural city and international tourist city. Xi 'an is the largest and most important base of scientific research, higher education, national defense science and technology industry and high-tech industry in central and western China, an important aerospace industry center, machinery manufacturing center and textile industry center in China, an important weapon manufacturing place in China and the only large aircraft manufacturing place in China. With a solid industrial base, it is one of the largest central cities in science and technology of west china with the strongest strength and the most complete industrial categories. 19361February 12, China Kuomintang generals Zhang Xueliang and Yang Hucheng launched a protest in Xi 'an, forcing President Chiang Kai-shek of the Republic of China to resist Japan. Also known as the Double Twelve Event.

From 1936 to 12, the Xi Incident led by patriotic generals Zhang Xueliang and Yang Hucheng of the Kuomintang and its peaceful settlement were important events in the history of China. On the basis of cooperation between the two parties, it played an important role in promoting the anti-Japanese national United front.

At that time, in the northwest, the main forces of the Kuomintang army centered on Xi 'an were the Northeast Army led by Zhang Xueliang and the 17th Route Army led by Yang Hucheng. Neither of these two armies is Chiang Kai-shek's clique, and has been repeatedly excluded. They were extremely dissatisfied with this, especially the Northeast Army. In the past, it blindly implemented Chiang Kai-shek's non-resistance policy and abandoned the Northeast, which was spurned by the people of China. Later, it was ordered to "suppress * * *", which caused heavy losses and was deeply felt by the whole army. After the Wayaobao meeting, China's * * * production party vigorously carried out the work of these two armies through various channels, strengthened Zhang's determination to resist Japan, and made the party's anti-Japanese national United front policy win first in the northwest.

Xi 'an was liberated on May 20th, 1949. After the founding of People's Republic of China (PRC), Xi 'an was once the seat of the Central Northwest Bureau and the Northwest Administrative Committee (the Central Northwest Bureau and the Northwest Administrative Committee were abolished). Municipalities directly under the central government: 1954 changed to provincial cities. Now it is a sub-provincial city. After more than 50 years of construction and development, Xi has formed a relatively complete urban service system with industrial system, and has become an important scientific research, higher education, national defense science and technology industry and high-tech industrial base in China, as well as a financial, scientific, technological, educational, tourism and business center radiating to the central and western regions in the north.
