In the winter of 1937, the Japanese Kwantung Army launched the “Three Rivers Crusade” against the Northeast Anti-Japanese United Army according to their three-year “rectification” plan, and the struggle of the Anti-Japanese United Army entered the most difficult period.In the autumn of 1938, the fierce battle caused a small team of the Northeast Anti-Japanese United Army to suffer heavy losses. Before breaking out, the platoon leader “Old Shandong” agreed with the soldiers that the survivors would go to the eight pines outside Songlin Town, Mudanjiang, carve their numbers on the trees, and regroup and return to the team.From then on, “Old Shandong” and five other anti-Japanese fighters embarked on a life-and-death journey back to the team. Some people were separated, some died, some betrayed, and some joined the 88th International Brigade to start new training and fighting.In 1945, on the eve of the victory of the Anti-Japanese War, three soldiers who joined the 88th International Brigade returned to the Northeast with a secret mission, and won over their comrades who had wavered in their thoughts to rejoin the team and complete the arduous task together.(Source: Chinese = Weibo || Translation = MDL)
