24. Summary
Nuclear physics in China developed rapidly, driving by CSR, BRIF, CARR, and future facilities and research projects
CSR, BRIF and new project will open up exciting research opportunities in nuclear physics
We would like to collaborate with foreign colleagues, especially for the active research and recruiting of user groups after the facility commission
