Are a large part of the current Northeast people descended from Shandong people?

Now the real northeast people are only two percent good. The real northeast person is Manchu. Now the northeast is full of Han people. Most of them are from Shandong and my family is from Henan. Shandong has the largest population in our village. I remember when I was a child, my grandmother quarreled with Shandong people and called them Shandong bonzi. I remember my grandmother also spoke Henan dialect, until she gradually became Mandarin, but she always called girls Ni, saying that Henan generally spoke Mandarin. My grandparents want to go back to Henan until they die, but family conditions don't allow it. I always thought I was from the northeast, because I was born and raised in the northeast, but I came to Tianjin 12 years. I have stayed in the northeast for a long time and will develop in Tianjin in the future.
