You can't. The use of funds of the National Natural Science Foundation needs to strictly abide by regulations and budgets, and cannot be used at will. The use of funds in the first year exceeds the budget, so it is necessary to adjust the budget or apply for additional funds from the superior. If there is illegal use of funds, it will be punished and held accountable. Therefore, when using the funds of the National Natural Science Foundation, we must strictly abide by the regulations and budgets to ensure the legality and compliance of the use of funds.
