From July 10th to 21st, 2023, the Sino-German Summer School of CDZM was held in Germany. 24 undergraduate students and two accompanying teachers visited Karlsruhe Institute of Technology, the Hirschvogel Group, and the Ruhr-University of Bochum. They listened to professional reports, visited the forming technology factory, the learning factory, and the Bochum Intelligent Engineering Center (in German: Zess), fully understanding the current frontier research topics and practices in the field of mechanical engineering, the German high education system, and German language learning. This trip laid an important foundation for future study and life in Germany.
