Which city in the north is good?

The better cities in the north should be Beijing, Tianjin, Baotou, Dalian, Ann and Qingdao. Anyway, I prefer Baotou, which is the first batch of megacities in China, an important heavy industry base and railway and highway transportation hub in the north, the core city of Hu Bao-Hubei urban agglomeration, a civilized city, a sanitary city, a livable city and the largest brand-level city in Inner Mongolia. Life and work are good.
