Today, 107 years ago, on August 10, 1918 (Lunar Calendar July 4, 1918), the Swedish monetary system was reformed. On August 10, 1918, the Swedish monetary system was "reformed" by the "Golden Bond Regulations". The proposed unit was named "Golden Dollar", the amount of gold contained was set to differ slightly from the amount of gold contained in the Japanese gold circles, completely with the Japanese gold as the standard, and borrowed 80 million yuan from the Japan-controlled North Korean bank. But the amount still exists as the reserve of the "Golden Dollar" issued by the North Korean bank, and is actually the reserve of gold issued by the Bank of Japan as the gold bill. This integrates the entire financial system of the city of China fully into the Japanese financial system.
