"Being an observer is a great opportunity because it bridges the gap between theory and actual reality," Chouhan said. "It's one thing to read about rural development on paper, but using photos, videos, and real field data makes these lessons genuine and easy for other developing nations to learn from."

　　Abdullaev said international students should go beyond simply describing China's achievements. "Our job is not to say 'China is amazing' and go home. It is to turn what we saw into something another country can actually use," he said.

　　Teng Lingjian, chairman of the Hangzhou Qiantang Center for Contemporary Internationalization Studies, said agriculture provides common ground for cooperation among BRICS countries. "When international students take successful entrepreneurial experiences back to their countries, this kind of visible result is what makes technology sharing truly effective," Teng said.

　　At the same time, the center plans to take a more proactive approach by sending its agricultural technologies, entrepreneurs and young talent to BRICS countries. "We hope to have deeper communication and cooperation with local agricultural projects and researchers," Teng said.

　　The final goal is to address major issues of common concern among BRICS countries, such as food security, he added.
