The people of Harbin are mainly ethnic Han Chinese, mostly hailing from Shandong and Hebei provinces. In the 1920s and 1930s, many overseas immigrants flocked to Harbin, mainly Russians. The Harbin people are influenced by non-natives and immigrants, so they have developed diverse foods and cultures. The food in Harbin could be divided into Northeast China, Shandong and Beijing cuisines. Russian food, lieba (a kind of big bread), sausage and soup have become ordinary table food. Harbin people are also influenced by ethnic food customs. They like to eat sticky rice cake, sticky bean bread, corn cakes and millet.
