On Dec. 31, 2024, our group held its annual campus tour. Led by Profs. Zhang, Hao, and Chen, all members toured the PKU campus, taking group photos at iconic spots such as the library's East Gate, Weiming Lake, the West Gate, and the office buildings.

      That evening, Prof. Zhang invited Profs. Wei, Hao, and Chen to join the group for a dinner gathering. During the banquet, Prof. Zhang presented the "Laboratory Outstanding Individual of the Year" certificates to four students: Yang Yuzhong, Huangfu Xinlei, Chen Yu, and Song Shuangji. The recipients gave brief acceptance speeches. New members of our group also spoke in turn, expressing their gratitude and extending New Year wishes to teachers and peers. Profs. Wei, Hao, and Chen shared their good wishes for the group as well. Finally, Prof. Wei concluded the evening with a summary, wishing everyone good health and success in their research in the coming year. Happy New Year to all!
