​With deep sorrow, we mourn the passing of Professor Chen Ning Yang, who served as a member of the Board of Directors of Tsinghua Education Foundation (N.A.) Inc. from 1997 to 2017. Professor Yang’s vision and wisdom were instrumental in the founding of the Foundation, which was established under his suggestion in 1997. His lifelong dedication to science, education, and the Tsinghua community continues to inspire us. We are profoundly grateful for his guidance and contributions, and his legacy will forever remain a part of our mission.
