Zhang stressed that the spirit of sacrifice and dedication from those days continues to inspire generations.

"Even today, many people in Dandong contribute their efforts to the friendship between China and the DPRK," she said.

Zhao Fengqi, a faculty member at Liaodong University in Dandong, is a prime example of this spirit. He worked for a year at the Representative Office for the Commemoration of Martyrs of the Chinese People's Volunteers in the DPRK, responsible for honoring the fallen Chinese soldiers.

"In 1950, my grandmother enlisted as a medic with the CPV, treating the wounded in the rear areas of Dandong," Zhao said. "Her spirit of dedication and the example she set have given me a deeper understanding of the history of the CPV."

Last year, after a rigorous selection process, Zhao was assigned to Pyongyang to undertake commemorative work for the martyrs of the CPV, an assignment he gladly accepted.

"In regular interactions with DPRK counterparts, we've found them to be extremely meticulous and friendly," he said. "They place great importance on our efforts to honor the martyrs of the CPV and have demonstrated a high degree of dedication and responsibility in the maintenance and management of the memorial parks."
