As the support of resource-based enterprises, the vast majority of enterprises, institutions and commercial services in Daqing still live around the word "oil". Sadly, at present, most people have no sense of crisis, shouting the slogan of building a century-old oilfield and enjoying themselves. In this way, enterprises, institutions and commercial services living around the oil field will one day disappear with the exhaustion of oil, repeating the mistakes of the famous big oil field cities in the former Soviet Union.
