One of the most important functions or functions of the Natural Science Foundation is to train graduate students and participate in projects. It is only natural that the person in charge of the natural fund projects should pay research funds to graduate students. If you only participate in the project in name, there is no money at all.
The National Social Science Fund is mainly for scholars engaged in basic research in key universities and Chinese Academy of Sciences, not for all teachers and researchers in the country, so there is no need for extensive mobilization.
