Even to other chinese dongbei folks are not viewed favorably. From what I have seen and heard both from talking with Chinese folks as well as reading their discussion boards they will view folks who are from there as being ill tempered, prone to alcoholism(even for China!), unwilling to be reasonable, and flat out bullying. I myself find folks from this area to be less willing to think for themselves and more willing to live life with the mantra of "follow the biggest bully on the block". Their mentality is slavish even for China. Be very, very careful when you're dealing with folks from this area.
