On January 26, 2026, we held a dinner to celebrate the 5th anniversary of the CCREM group. We invited Prof. Xi, Prof. Wei, and Prof. Hao to join the celebration. They shared their congratulations to our group and their hopes for us. Graduated students also talked about their work experiences and personal reflections. Finally, Prof. Zhang thanked all members and expressed his hopes that everyone would stay healthy, make good progress in their studies, and work together for a better future of the CCREM Laboratory.
