To support his family and fund his education, Shan took up a temporary construction job during summer vacation after his gaokao, earning a daily wage of 200 yuan ($27.5). Government student loans and charitable funds were also in place to assist his studies.

At Tsinghua, Shan transitioned from a "construction site boy" to a regular student, immersing himself in his studies. "Coming to Tsinghua, I hope to contribute more to the country, engage in cutting-edge research, and truly make a practical impact on the people," he said.

Inspired by a lecture from Major General Zhu Fengrong, a 1966 Tsinghua alumnus, Shan realized the importance of contributing to the nation and society. This reflection led him to join the People's Liberation Army Navy during his junior year, seeking a new environment to deepen his understanding and growth.
