The National Natural Science Foundation is a national fund project supporting scientific research, which has important academic and social significance. If your research topic meets the application requirements of the fund and passes the examination, then there is hope of winning the bid. However, it is difficult to win the bid because of the large number of fund applications and fierce competition. Applicants can prepare carefully and improve their competitiveness according to official guidance. In addition, even without the support of the National Natural Science Foundation, we can still try other channels to seek the support of scientific research funds.
