What should you pay attention to when contacting Shandong people?

I am from the Northeast, and I know Shandong people relatively well, because there are more Shandong people immigrating from the Northeast, and there are also Shandong people among my relatives. First of all, Shandong people are simple, capable, and stubborn in character. There are very few people who do bad things, and there are very few petty thefts. Secondly, Shandong people are very family-oriented, simple and tolerant in trouble. Finally, Shandong people feel very warm and honest when you first meet them, but you can't make deep friendships because they are easy to care about and not generous enough. They often harm the interests of others for the sake of their own family. Although there are very few people who commit great crimes, they are trivial in life. He never gave up on the little things.
