Mr. Tan Qixiang pointed out: After Yongjia, "Although the Central Plains left Li as the national power, it was crowned by the gentry."

Although it is the general trend for the Central Plains to leave Li, it is especially popular among the crown gentry. "Biography of Wang Dao" said: "When Luo Jing was overthrown, there were sixteen or seven women in Zhongzhou who avoided the river." Although Jiangzuo was founded in the Eastern Jin Dynasty and the Southern Dynasties, their temples and rituals were dominated by people crossing the river and their descendants. According to the figures in Biography of Southern History, there are 728 people (excluding empresses, royalty and filial piety), among whom 6 are northerners, but 222 are southerners, so what they say is not empty talk. Naturally, then, the voices and teachings of the southeast people flourished, and they surpassed the northern soil. Confucius in the article said: "China, east of the Yangtze River, is ancient, and the place where clothes, gifts and music are worn is also there" (Zhong Shuo Wen Shu). Du You wrote the General's Code, in which he described the situation in Yangzhou (now Jiangsu, Zhejiang, Anhui, Fujian and Jiangxi provinces), saying: "After Yongjia, the emperor's mansion moved eastward, and he took refuge in clothes, but he was exhausted. Art, literature and Confucianism flourished. Today, although I am a cheap product, I keep chanting when I take it, and I am full of fans of Yan, Xie, Xu and Yu. "

South Xuzhou accepted the most diverse and numerous immigrants, and then the outstanding talents of the Southern Dynasties also produced more and the best quality in this area. Liu Yujia lives in Jingkou (Zhenjiang) and Xiao Daocheng Xiaoyan lives in Lanling (Wujin) south of Wujin, both of which belong to South Xuzhou. Therefore, Xiao Zixian called South Xuzhou, saying, "Since the Song Dynasty, the residence of Emperor Sang Zi has been rich and productive." Talents from South Xuzhou gather in Jingkou. Today, if we find out in biographies that Fan Yangqi, Liu, Dongguan Ju, Tan Daoji, Jin Xiang, Liu Cuipei, Xiao, Meng Huaiyu, Pingchang Anqiu, Xiang Jing, Peng Chenglu, Zhuge Lan, Hedong Yang and Guan Kangzhi all live in Jingkou.

There are many ways for Central Plains people to move south. For example, Hanshui River is the main road for Shaanxi-Gansu people to go south and southeast, so Nanzheng and Xiangyang are the second largest cities in the Han Dynasty and the second largest gathering place for Shaanxi-Gansu immigrants. Jinniu Road (that is, Nanplank Road) is a avenue for Shaanxi and Gansu people to go southwest, so all the overseas Chinese counties in Sichuan Province are near this road. At that time, the Han ditch had been dug through the Tongjiang River and Huaihe River, so Jiangdu at the southern end of the ditch and Zhenjiang and Wujin on the other side were the gathering places for immigrants from Shandong and northern Jiangsu. The tributaries of the Huaihe River are all in the southeast, so most people in Henan move to Anhui in the southeast, not to Hubei in the south.

The era of moving south can also be seen. It is the first time that refugees from Hebei, Shandong, Shanxi, Henan, Jiangsu, Anhui and other places have crossed the river and Huaihe River. In the third year of Taixing, Yuan Di, Huaide County was founded by overseas Chinese who crossed the river for the first time because of evil spirits. Later, overseas Chinese settled in Xu, Yan, You, Ji, Qing, He and Si counties in the north and south of the Yangtze River. Followed by Xu, Yanzhou and other overseas Chinese counties in the south of the Yangtze River.

Preface to Song Zhi: "Since the barbarians invaded China, Sri Lanka, Kyrgyzstan, Yong, Liang, Qing, He, Chong, Yu, You, and the equal country fell for a while, and the adherents crossed south, and the overseas Chinese set up a pastoral department."

"Preface to South Xuzhou": "The Jin Yongjia Rebellion, Youjing, Hebei, Qinghai, Binhe, Yanzhou, Xuzhou and other Huaibei refugees crossed the river, and Jinling County also had people crossing the river. Xu, Yanzhou or Jiangbei. There are also overseas Chinese standing in secluded places in Jiangbei, Hebei, Qinghai and Sizhou. "

"Preface to Divide States": "When crossing the river, overseas Chinese will also set up Xu Fenbang".

Preface to Jinzhi Xuzhou: "Ming Di is located in Nanpei, Nanqinghe, Nanpi, Nandongguan, Nanpingchang, Nanjiyin, Nanpuyang, Nantaiping, Nantaishan and Nanjiyang, which belong to Xu and Yanzhou".

At the beginning of the emperor's accession to the throne, civil strife and foreign invasion caused chaos between Jianghuai. Therefore, this is the second time that Huainan people and overseas Chinese in the north have crossed the river south.

"Song Zhi" Huainan County, Yangzhou: "The Central Plains was in chaos, and the tiger's mouth repeatedly invaded, and Huainan people crossed the south. At the beginning of the emperor, Su Junzu was in the Jianghuai rebellion, and the mouth of the lake was as big as it was. Many people in Jiangnan crossed the river, and overseas Chinese in Jiangnan were established in Huainan County.

South Xuzhou: "In the four years of Jin Xian Di, Sikong Chi Jian moved refugees from Huainan to Jinling County."

Nanyuzhou: "In the fourth year of Emperor Xianhe, overseas Chinese established Yuzhou and ruled Wuhu".

Since Kang and Mu, "Hu Wu rebelled against chaos", and the Central Plains was in a state of chaos, year after year, and Guan Yu suffered the most serious damage. Therefore, most people in Shaanxi-Gansu area have left the Hanshui River Basin in the south. When Huan Wen destroyed Shu, it was the third time that someone went south to Sichuan.

"Song Zhi" Yongzhou: "Hu Wu chaos, Yong, Qin refugees more south. Jin Xiaowu started with overseas Chinese establishing Xiangyang in Yongzhou and establishing overseas Chinese county.

Qin Zhou said, "Jin Xiaowu was reinstated and sent to Xiangyang. Stone, in Nanzheng,No. Hanzhong ". West Jingzhao County and West Fufeng County: "Sanfu refugees left Hanzhong at the end of Jin Dynasty and settled overseas".

Angu County, Yizhou: "When the Emperor was buried in Jin Dynasty, the refugees entered Shu and settled overseas". Huaining County, Jinxi County and refugees from Qin, Yong, Guan and Long established Jin 'an Emperor.

Guanluo, Beiping, Song Wudi, the land of Qing, Ji, Si and Yan. Since Song Wudi, both the North and the South have suffered losses, but the Song people have been defeated repeatedly. Emperor Wu of the Han Dynasty lost his state, Emperor Wen of the Han Dynasty lost his state, and wei ren invaded the south on a large scale, so that Guabu (southeast of Liuhe County) arrived, and there were no northern courts in Huaibei, Yuzhou and Huaixi, so many people crossed Huaishui in the south; It was the fourth attack by Wendi on the number of people in the world, and Guanlong refugees took refuge.

"Song Zhi" Sizhou: "When the young emperor was at the beginning of Jingping, Sizhou recovered Beilu, and when the Emperor Wen was at the end of Yuanjia, the overseas Chinese established Runan."

North Huai County, North County, North Xia Pi County, South Yanzhou Dongguan County, as well as overseas Chinese in the late Song Dynasty.

Yanzhou: "At the end of the Song Dynasty, Huaibei fell, and overseas Chinese established Yanzhou and sent it to Huaiyin." Overseas Chinese established Dongping County in Huaiyin and Jinan County in Huaiyang. In the fifth year of Taishi, overseas Chinese established Gaoping County on the border of Huainan and dangtu county.

Xuzhou: "In the era of Ming Di, Huaibei was invincible, and overseas Chinese established Xuzhou to rule the clock." .

Qingzhou: "Ming Di lost the Huai River and overseas Chinese in Yuzhou established Qingzhou".

Fengyi county, Yongzhou, Fengyi county, Sanfu refugees went out of Xiangyang and Hanzhong, and Yuan Jiaqiao Li.

Yuan Jiazhong and overseas Chinese stood in Jiannan, Nanxinba County and Nanjinshou County of Yizhou.

"Qizhi" Liangzhou: "In the Song and Yuan Dynasties, Jiazhong and ... attacked several times, and the refugees in Guanlong took refuge and naturalized."

Since then, Wei Yi has been in the north, while Qi, Liang and Chen usurped the south. The trend of controlling chaos is not what it used to be, and the wind of the people moving south in the Central Plains has also been stifled. Wei Bing often goes to the Yangtze River and Huaihe River, which makes many southerners move northward. Emperor Xiaowen stood up to worship Confucian classics and was immersed in China culture, so the gentry in the Central Plains took refuge in Jiangzuo, and they were eager to return to China. Since Jinjiang left, the immigration trend has changed. The cultural and material resources of the Central Plains began to revive slightly. However, the south crossing is a positive current, and the north turning is an echo. After the Sui and Tang Dynasties, the prestige ratio between the North and the South was not the same as that of the Han and Wei Dynasties.
