A Brief Introduction of Guan Yi Du Nan

Take the crown to the south and make a dress to the south. Liu Zhiji, a historian of the Tang Dynasty, wrote Yi Li in Shi Tong. This article originally only refers to the chaos in the world at the end of the Western Jin Dynasty, when the gentry of the Central Plains fled south with them, and the Central Plains civilization or regime moved south. Houyi Guannandu has gradually evolved into a mature classic, which refers to events such as gentry and literati taking root in the south to avoid chaos. In the history of China, there were three large-scale population migrations due to unrest, namely: at the end of the Western Jin Dynasty, the Jin and Yuan emperors crossed the river, and Jiankang (now Nanjing) established the Eastern Jin Dynasty as the capital; After the "An Shi Rebellion" in the Tang Dynasty, scholars from the Central Plains fled to Jinling (now Nanjing) to establish the Southern Tang Dynasty. At the end of the Northern Song Dynasty, Song Gaozong crossed the river and established the Southern Song Dynasty with Lin 'an (now Hangzhou) as its capital. Among them, some historians only admit that it was "crossing the south with a crown" twice at the end of the Western Jin Dynasty and the end of the Northern Song Dynasty (some historians also call it all), but in literary application, there are also many people who have been dubbed "crossing the south with a crown" three times.
