Historical events in Shanxi during Sui and Tang Dynasties

At the end of Sui Dynasty, Li Yuan and his son set out for Jinyang (now Taiyuan), then seized Chang 'an, established the Tang Dynasty, and later designated Taiyuan as the northern capital of the Tang Empire. At the end of Yuan Dynasty and the beginning of Ming Dynasty, there were wars and famines in the Central Plains for years, and Shanxi, especially the southern part of Shanxi, became the main area of immigrants in the early Ming Dynasty because of its economic prosperity and dense population. Over the past half century, Shanxi has immigrated more than a dozen times. The pagoda tree in Hongtong County was a major immigration station at that time. This is where the phrase "Ask where my ancestors are, Sophora japonica in Hongdong, Shanxi" circulated in many parts of the country comes from.

Emperor Taizong and Li Shimin founded the Tang Dynasty. As a result, Shanxi was regarded as the land of Longxing by Emperor Taizong, Shanxi was always regarded as the belly of the Tang Dynasty, and Taiyuan was named as the "northern capital" and "Beijing" of the Tang Dynasty. During the Tang Dynasty, Shanxi was famous for its special geographical location and developed economy and culture.
