Why is Northeast Dialect so similar to Mandarin? Are Northeasters descendants of immigrants from Beijing?

As we all know, Putonghua is a language with Beijing dialect as its basic tone and vernacular as its grammar. Besides Mandarin, there are many dialects in Chinese in China, such as Cantonese, Hakka and Minnan. One of the dialects is not Mandarin, but it sounds like Mandarin, and that is Northeast Dialect. Northeast dialect is a dialect in the northeast of China. Northeasters are not descendants of immigrants from Beijing, but because they are very similar to Mandarin, Northeastern dialect is very similar to Mandarin.

First of all, Putonghua evolved from the ancient Beijing Mandarin. According to history, we can know that the standard language of Mandarin we speak now was established in the Republic of China. At that time, the Republic of China will formulate standard Chinese based on the grammar of northern Mandarin and Beijing Mandarin, and will not change Mandarin into Putonghua until after the establishment of People's Republic of China (PRC). At that time, the standard language of the Republic of China was formerly the Mandarin of Ming and Qing Dynasties. In the Ming dynasty, Jinling Yayan was used as an accent, which was an ancient Nanjing mandarin. Later, after Yongle moved to the capital, the political center of gravity moved northward, which led to the northern pronunciation and accent of Mandarin in Ming and Qing Dynasties. Then, after a long period of time, Beijing Mandarin gradually came into being, replacing Nanjing Mandarin as the mainstream language, and then gradually became modern Mandarin.

Then, Northeasters are not descendants of immigrants from Beijing, but dialects in the north are similar, which leads to the similarity between Northeast dialect and Mandarin. At the end of Qing Dynasty, Northeast China was coveted by foreign enemies. The Qing government began to open the northeast, guiding a large number of Han people from northern areas to migrate to the northeast. At that time, Han people from Shandong, Henan, Hebei, Shanxi and other regions immigrated to the northeast, and the largest number of them were from Shandong. At that time, the wave after wave of migration of Han people led to the northeast region becoming a place where Han people lived in all directions. The immigrant structure is very diversified, which leads to the interaction between immigrants and local aborigines, and the northern dialects in all directions also influence each other, which is very similar to the formation process of Putonghua, so the northeast dialect has also become very similar to Putonghua.

Finally, although it sounds similar to Dongbei dialect, in fact, Dongbei dialect in different regions is different, which is related to the source of ancient immigrants and the proportion of collusion.
