Are a large part of today's Northeastern people descended from Shandong people?

Two percent of the real Northeastern people are now good. The real Northeasterners are Manchus. Now the Northeast is all Han Chinese. Most of them are from Shandong. My family is from Henan. We are a village. Shandong has the largest number of people. I remember when I was little, my grandma would quarrel with the Shandong people and call them Shandong Bangzi. As far back as I can remember, my grandma still spoke Henan dialect. It was only after I was twenty years old that my grandma gradually changed to Mandarin. But when you call a girl, you always call her Ni. Henan is generally referred to as Guanli. My grandparents wanted to go back to Henan until they were dying, but my family's conditions did not allow it. I always felt that I was from the Northeast, because I was born and raised in the Northeast. But I have been in Tianjin for 12 years, and I want to stay with you. The Northeast has been around for a long time, and it will develop in Tianjin in the future
