This novel uses the Great Wall Anti-Japanese War as the historical background, respects historical facts, and pays tribute to real events such as the 29th Army's Saber Team, the Battle of Xifengkou, and the anti-Japanese struggle of the people along the Great Wall. It incorporates reasonable fictional elements to show the national spirit of the Chinese people who are indomitable and bloody in resisting the enemy. Even if the mountains and rivers are not restored, the Snow Wolf will not retreat; the spirit of heroes will never be extinguished, and the war of resistance will never end.
