"I don't have a money printing machine at home. Where can I exchange so many central bank notes? I immediately called back the Bureau's headquarters. Thinking that exchanging central bank bank notes is extremely difficult and does not meet the two to one ratio, the difference is too large, the write-off requirement cannot be met, ask the manager to exchange all the money for strategic materials such as tung oil and valuable feathers equivalent, then exchange them for China National Reserve Bonds after they are transferred to the Shanghai stock exchange, and the difference will cover the gap.” Xu Ruiyang said.
