Take management measures, that is, you can take risk isolation measures to separate different risk units, limit risks to as small a range as possible, and avoid a chain reaction or mutual involvement when a certain risk occurs, such as locating a woodworking factory far from the on-site office; Risk diversification measures can also be taken to reduce the overall risk pressure by increasing risk units, so as to achieve the purpose of sharing the overall risk, such as using multiple currency combinations to pay in the settlement of foreign-related projects and diversifying exchange rate risks.
