A province rich in coal, but with inherent deficiencies. No matter how much life the northern cities breathe into Tokyo, Hokkaido's revitalization has failed for many years. Tokyo's decision to influence the "new and old kinetic energy conversion" in 2018 resulted in cutting off a tenth of the businesses and employment in the leek province. Some of the old kinetic energy enterprises and local contracts were forced to be cut off. What's even more amusing is that a few major old kinetic energy enterprises turned to the Yangtze River Delta and Pearl River Delta. The world is a huge grassroots team, trash.
