豫湘桂会战
Soon after arriving in Chongqing, Hu Die starred in the film "The Road to Nation Building" to aid the war effort. While she was filming on location in Guilin, the Japanese launched the major offensive Operation Ichi-Go. The film crew lost all their equipment, and had to join the tens of thousands of refugees fleeing the war front on foot. "The Road to Nation Building" was Hu Die's only unfinished film, and she later described the incident as "the most tragic moment of my life".
