Why did the gentry of the Central Plains come to Fujian to be Hakkas? "

The Central Plains people who moved south mainly lived in the middle and lower reaches of the Yangtze River, and some of them moved to the mountainous areas at the junction of Jiangxi, Fujian and Guangdong provinces, where they "paved the way for mountains and opened up wasteland" and established new homes. In the late Southern Song Dynasty, Jin Bing invaded Jiangnan many times, forcing the Central Plains immigrants who had settled in Zhejiang, Jiangxi, Jiangsu, Hunan and other places to migrate again and arrive in Tingzhou (now Changting, Fujian). A large number of immigrants from the Central Plains moved in, which changed the local economic situation and cultural features, making "Ting customs quite like Zhongzhou". These immigrants later moved to Meizhou and other places from Tingzhou and Ganzhou to avoid the Yuan Army. They are called "Hakkas" because they moved in from other places and are obviously different from the local aborigines.
