Talk about your hometown.

My hometown Xi 'an, known as Chang 'an in ancient times, is one of the four famous ancient civilizations in the world, ranking first among the ancient capitals of China. It is the capital with the longest history, the most dynasties and the greatest influence in China, the cradle of the Chinese nation, the birthplace of Chinese civilization and the representative of Chinese culture. Today, Xi is the capital of Shaanxi Province, one of the seven regional central cities in China, the innovation center of knowledge and technology in Asia, the largest central city in the China section of the New Eurasian Continental Bridge and the Yellow River Basin, the aircraft manufacturing base in China, and the largest and most important scientific research, higher education, national defense science and technology industry and high-tech industry base in the central and western regions of China. In the Guanzhong-Tianshui Economic Zone Development Plan issued by the state in 2009, Xi 'an was listed as the third "international metropolis" in China after Beijing and Shanghai.
