The three northeastern provinces are not Han Chinese.

During the Shang Dynasty, Dongyi migrated from Shandong to the northeast to fight against the Shang Dynasty.

During the Spring and Autumn Period and the Warring States Period, people in the Central Plains avoided chaos.

During the Han Dynasty, there were Han people in the northeast.

Jin inherited the Han Dynasty.

In sixteen countries, there are still Han people, and the Northern Yan was built by Han people.

In the Tang Dynasty, after five chaos, the number of Han people in Northeast China decreased and Han people became chaotic.

Liao plundered the Han people from the Central Plains to avoid the influx of the Five Dynasties War, and the Khitan stood side by side with the Han people.

Jin, Yuan and Han are slaves in Northeast China, and there are many of them.

In the Ming Dynasty, a large number of Han immigrants mainly concentrated in Liaoning.

The Qing dynasty first killed the Han people in Liaoning, and a large number of Han people were taken into slavery.

On the one hand, Manchu abused and slaughtered Han people in Northeast China. On the other hand, I am afraid that there will be too many Han people in Northeast China and lose the "land of Longxing", so I built trenches in the closed area and planted willows along the trenches, which is called wicker edge. Also known as Shengjing side wall, Liucheng and Tiaobian.

During the Kangxi period of Shunzhi (1644 ~ 1722), wicker borders were built in Liaohe River Basin and parts of Jilin Province. People are prohibited from crossing the side wall to hunt, graze and collect ginseng. The wicker edge of the Liaohe River Basin starts from Fengcheng South of Liaoning Province in the south, passes through Xinbin East in the northeast, reaches Weiyuanbao in Kaiyuan North in the northwest, and then connects with the Great Wall in the southwest through Shanhaiguan North, with a circumference of more than 1,900 miles, which is called the "old edge", also known as the "Shengjing side wall". From the northeast of Weiyuanbao to the present, it is 690 miles long and is called the "new border".

Due to the blockade of the Qing Dynasty, until the Guangxu period, the population in the northeast of Nuoda was only 7 million (most of them were Han people in Shandong and Hebei, or descendants of Han slaves who were abducted).

The northeast really developed, but it was precisely in the Republic of China era, that is, the Zhang era. In order to stabilize the frontier defense and cope with the Japanese-Russian aggression, Beiyang government and Zhang's father and son immigrated to Northeast China in large numbers from Shandong, Hebei and even Henan and Anhui with a population of 3 million per year, which fundamentally changed the population structure of Heilongjiang and Jilin. By 1933, the population of Northeast China has reached 2965438+ 10,000! In just 10 year, the desolate northeast under the rule of Manchu in the past and the northeast ravaged by Japan and Russia became the most developed region in China. Railways are 85% nationalized and telecommunications equipment is 98% nationalized. The salary of professors in Northeastern University is six times that of Peking University, about 3,000 yuan, which exceeds the salary of the prime minister. 1927 can produce engines (the most advanced Nordic equipment was introduced at that time), 1930 The first air-conditioned train in Asia was born in Dalian. Even Dr. Sun Yat-sen praised Zhang, saying that he developed the Northeast and made the people's livelihood in the Northeast surpass that of any other place in the country!
