including modern-day Fujian and Guangdong, further integrated the areas south of the Yangtze River into the Chinese cultural sphere. Han Chinese migrations The "Eight Great Surnames" were eight noble families who migrated from northern China to Fujian in southern China due to the uprising of the five barbarians when the Eastern Jin was founded, the Hu, He, Qiu, Dan, Zheng, Huang, Chen and Lin surnames. The different waves of migration such as the fourth century and Tang dynasty northern Han Chinese migrants to the south are claimed as the origin of various Chen families in Fuzhou, Fujian. Mass migrations led to southern China's population growth, economic, agricultural and cultural development as it stayed peaceful unlike the north. Yellow registers were used to record the original southern Han Chinese population before the migration and white registers were used to record the massive influx of commoner and aristocratic northern Han Chinese migrants by the Eastern Jin dynasty government.

In Luoyang a Wu quarter was set up for southerners moving north. Han Chinese male nobles and royals of the southern dynasties who fled north to defect married over half of Northern Wei Xianbei Tuoba princesses. Southern Chinese from the southern capital of Jiankang (Nanjing) were deported to the northern capital of Chang'an by the Sui dynasty after reuniting China. Han Chinese refugees from the five barbarian uprising also migrated into the Korean peninsula and into the Murong Former Yan state. Eastern Jin maintained nominal suzerainty over the Murong state until 353 as the Murong accepted titles from them. An official in the Murong state, Dong Shou defected to Goguryeo. Han Chinese refugees migrated west into Han Chinese controlled Former Liang.
