How many years has the history of Hakkas been? It's better to be more detailed.

Hakka, also known as Hakka clan, is an Huaxia-Han nationality with remarkable characteristics, and it is also one of the most widely distributed and far-reaching ethnic groups of Han nationality in the world.

The name "Hakka" originated in the late Ming and early Qing Dynasties, and was called by Siyi people who called themselves "Siyi people" in Jiangmen, western Guangdong at that time.

The word "Hakka" was later widely known because of Luo Xianglin's Hakka theory. After being promoted by Hakka scholars, it gradually became the name of the ethnic group, but some people did not like it.

According to the genealogy statistics of all ethnic groups at home and abroad (including Malaysia and the United States), there are six main migration periods:

The first time was when Qin Shihuang unified the whole country: Qin Shihuang sent a large number of soldiers and civilians to Lingnan in order to consolidate the newly acquired southern territory (namely Lingnan area).

After the end of the Qin Dynasty, Zhao Tuo, the prefect of Nanhai County, rose up, annexed Guilin County and Xiang Jun County as kings, and established Nanyue State independently. These soldiers and civilians settled in the north of South Vietnam.

Later generations called Beijiang Hakka.

The second time in the Yongjia period of the Eastern Jin Dynasty: due to the chaos of the Five Dynasties, Shanxi, Hebei and Henan provinces crossed the Yellow River one after another and crossed the Yangtze River from Anhui to the north of Jiangxi;

For the third time, in the Tang Dynasty, Nuozonggan was in office for two years: because of the Huang Chao Rebellion, the residents of northern Jiangxi moved to western Jiangxi, western Fujian (western Fujian) and southern Fujian (southern Fujian), eastern Guangdong (eastern Guangdong) and northern Guangdong (northern Guangdong);

The fourth time was at the end of the Southern Song Dynasty: this was a crucial period for Hakkas to move south to Guangdong.

As the Mongolian army went south, the Hakka ancestors in Jiangxi and Fujian entered eastern Guangdong (east) and northern Guangdong (north) with the defeated Song royal family.

The fifth time was in the late Ming and early Qing dynasties: due to the policy of filling Sichuan with Huguang, some Hakkas from Guangdong and Fujian moved to Sichuan. Non-pure Hakka counties mainly include Longquanyi, Xindu, Qingbaijiang, Yilong, Fushun, Renshou, Rongchang, Xichang, Longchang and Lu Xian.

The sixth time was after Zheng Chenggong captured Taiwan Province Province: after sending a large number of soldiers and civilians (including many Hakka soldiers and civilians) to fight against the Qing army failed, many Hakka people from Guangdong and Fujian opened up wasteland in Taozhu Temple, Liu Dui, Pingtung, Kaohsiung and East Rift Valley in Taiwan Province Province.

By the middle and late Qing Dynasty: after the Opium War, the national strength continued to decline, and the land shortage and population density in Hakka areas in Guangdong became increasingly serious, and a large number of Cantonese (including Hakkas) immigrated to Nanyang and other places.
