State-level funds are obtained by applying for state-level scientific research institutions, such as the National Natural Science Foundation, the Ministry of Science and Technology, and the Ministry of Health. Their project funds generally range from hundreds of thousands to millions;

Provincial scientific research funds are mainly obtained by applying for provincial natural and provincial scientific research programs and other provincial scientific research institutions, and the general funds are tens of thousands or hundreds of thousands (major key and scientific research projects).

In fact, there are no strict boundaries for the use of funds. For example, provincial projects can be used to apply for national projects at the same time. As a project, national and provincial funds can be used at the same time. As long as the project is completed and the expected goal is achieved, the funds can be used.
