Origin Story
话说当年抗日战争时期，八路军在敌后作战，面对装备精良的日军，他们并没有与之正面硬碰硬，而是采取了化整为零的战术。八路军将大的作战单位分解成许多小的游击队，神出鬼没地出现在敌人的后方，袭扰敌人的交通线，破坏敌人的后勤补给，有效地牵制了日军的兵力，最终为抗日战争的胜利做出了巨大贡献。
During the Anti-Japanese War, the Eighth Route Army fighting behind enemy lines, faced with well-equipped Japanese troops, instead of engaging in head-on conflict, they adopted the tactic of “dividing into small units”. The large combat units were broken down into many small guerrilla squads, appearing unexpectedly in the enemy’s rear, harassing their lines of communication, disrupting their logistical supply, effectively tying up the Japanese forces and making a huge contribution to the victory of the Anti-Japanese War.
