For 14 grueling years (1931-1945), the Northeast Anti-Japanese United Army stood as China's northernmost force of resistance against Japanese aggression. Deep in the forests of Jilin Province, their first guerrilla base was set up in a remote area called Hongshilazi. Spanning 32 square kilometers, this battlefield has become an active archaeological site, revealing more than 3,300 ruins and 900 artifacts. In this episode, we follow Meng Qingxu, the lead archaeologist behind the dig, as he reveals how the past is being pieced together.
