There's also a lack of trust for southern brands/EVs in the dongbei region (mostly among the older generation from what I've personally observed there) and since it was the birthplace of China's auto industry they tend to prefer ICE vehicles. There's also some resentment from feeling being left behind compared to the south, economic/demographics issues, and their charging infrastructure is not as good as the south's. They still do have quite a bit of EVs though, at least in the bigger cities, like most ride-hailing cars there are Hongqi E-Qm5s.
