Who can introduce me to Taiyuan, Shanxi?

Taiyuan is the capital of Shanxi Province, referred to as Bingzhou, or Bingzhou, or Jinyang in ancient times, or "Dragon City". Close to Fenhe River and surrounded by mountains on three sides, it has been called "Splendid Taiyuan City" since ancient times. The song "People say Shanxi has good scenery" is to highlight the beauty of Shanxi, especially Taiyuan, its capital. The center of politics, economy, culture, education, science and technology, transportation and information in the province is an important energy and heavy chemical city in China with metallurgy, machinery, chemicals and coal as its pillars and the export of energy, raw materials and mining machinery products as its main features. It is one of the most famous historical cities in northern China.
