In this way, the RMB will enter the account of the enterprise and be used by the enterprise, and the amount of money in circulation will increase. Once it reaches a certain level, it will lead to inflation. Inflation refers to the amount of money in circulation.

Once inflation and bubbles appear, the economic order will become more chaotic, and producers, investors and consumers will become at a loss, which will bring many adverse economic consequences.
