Reasons for the migration of ancient Hakkas.

The origin of Hakka began in the Rongbaiyue period in Lingnan, Qin Zheng, and then there were five major migrations:

The first great migration: In the first year of Yongkang in the Western Jin Dynasty (AD 300), the "Eight Kings Rebellion" occurred in the Central Plains, and then the people's struggle against gold broke out, which greatly shook the rule of the Western Jin Dynasty. At this time, the Xiongnu, Xianbei, Qiang, Bian, Jie and other ethnic minorities in the north took advantage of the situation, taking their own land as king and fighting with each other endlessly, which plunged the Central Plains into a turbulent situation of "five chaotic flowers blooming". After the demise of the Western Jin Dynasty, the Central Plains became the world of Hu people, who abandoned farmland, herded cattle and sheep and enslaved Han people. The enslaved Han people moved south on a large scale. They entered Xiangyang from the Central Plains via Nanyang, Henan, and entered the Yangtze River along the Hanshui River to Hubei, Anhui and Jiangsu. To the south, from Jiujiang to Poyang Lake, or enter the mountainous area of southern Jiangxi along the Ganjiang River. This trend has continued for more than 70 years, with a population of12 million.

The Second Great Migration: Since the "An Shi Rebellion" in the Tang Dynasty, the situation in the whole country has turned from prosperity to decline, and there has been a situation of division of provinces. In Canada, the original famine continued year after year, the government cracked and exploited, the people were in dire straits, and many fireworks in urban and rural areas were cut off, which was a depression. Soon, the peasant uprising led by Wang Xianzhi and Huang Chao broke out. The insurgents marched into the Central Plains and moved to Yu Sheng, north and south of the Yangtze River. These places are the areas where the Han people moved south for the first time. Only Gannan, southwestern Fujian and northeastern Guangdong are the "promised land" affected by the war, so most of the Hakka ancestors in these provinces went back to the Ganjiang River from Jiujiang and settled in the triangle of Gannan, western Fujian and northeastern Guangdong today. This southward migration lasted for more than 90 years and lasted until the Five Dynasties after the Tang Dynasty.

The third time was the great migration in the formation of Hakka clans: in A.D. 1 126, the Jingkang disaster occurred, and Kaifeng, the capital of the Northern Song Dynasty, was captured by Jin Bing. Song Gaozong Nandu became emperor in Lin 'an (now Hangzhou) and established the Southern Song Dynasty. Millions of people moved south with Emperor Gaozong. After Jin people entered the Central Plains, they seized private land and promoted slavery. In order to escape the war, the Han people in the Yellow River valley crossed the river south again. Later, Mongolia destroyed gold and entered the Central Plains. As the Mongols pushed southward, the borders of Jiangxi, Fujian and Guangdong became the battlefields in the Song and Yuan Dynasties. In order to seek a peaceful environment, the Hakkas who moved here earlier continued to move south and entered Meizhou and Huizhou in eastern Guangdong. Because the household registration at this time is divided into "subject" and "object", all immigrants and naturalized people are included in the "object". And "Hakka" calls itself "Hakka".

The fourth Hakka migration: First, it was influenced by Manchu entering the Central Plains. When the Qing soldiers entered Fujian and Guangdong, the righteous Hakkas came forward to call on the masses to raise righteousness against the Qing Dynasty, and were forced to scatter everywhere after their failure. Some went to Taiwan Province Province with Zheng Chenggong; Moved to northern Guangdong, central Guangdong and western Guangdong; Some went to Guangxi, Hunan and Sichuan. The second is the expansion of Hakka population. After more than 200 years of development, the Hakka population in the border areas of Jiangxi, Fujian and Guangdong has greatly increased, but there are few local Shan Ye and insufficient agricultural harvest, so they want to develop abroad. It coincided with the immigration movement of "moving lakes and filling Sichuan" initiated by the Qing government during the reign of Kangxi. As a result, a large number of Han people who moved from the Central Plains to the two lakes and Guangdong entered Sichuan.

The Fifth Hakka Migration: During the reign of Xianfeng and Tongzhi in Qing Dynasty, the Taiping Heavenly Kingdom Movement led by Hong Xiuquan, with Hakkas as the basic team, moved south for more than ten years. After the fall of Tianjing, the insurgents were destroyed and the people fled. During this period, there was a gun battle between natives and guests in central Guangdong, which lasted for 12 years. In order to solve the disputes between the aborigines and the Hakkas, the Qing government specially designated Chixi area in Taishan to resettle the Hakkas. The unrest caused the Hakkas to start another great migration, moving to Hainan and Guangxi, and even crossing the ocean to make a living.
