Harbin Old Road is called 22 1 National Road. In the early 1980s, an old couple in the village opened a small restaurant by the roadside to provide a place for pedestrians on Harbin-Datong Highway to rest and eat. This delicious stew of live carp with tofu and vermicelli spread like wildfire. Later, 47 fish stew restaurants were opened on the road where the 22 1 national highway (known locally as "Hatong Road") passed less than 1000 meters from Demoli village, which made Demoli's fragrance and fame stew.
