After the July 7th Incident in 1937, when Peiping fell, Li Suzhen, a descendant of the chivalrous thief Yanzi Li San, organized the "Chivalry Girl Society" and assassinated many Japanese invaders officers. The commander of the military police, Amu Saburo, had trouble sleeping and eating, and asked Tokyo to call in the jujitsu master Oda Shiro. Oda had lived in China for more than ten years and was a disciple of Elder Changde of the Shaolin Temple. He was highly skilled in martial arts. He used the preparation of the Sino-Japanese Martial Arts Research Society as a bait to use the brothers who only talked about loyalty to the country and had no idea of national integrity as accomplices of traitors. The chivalrous woman fought against powerful enemies repeatedly, and the stronghold in the underground palace of Princess Tomb was almost destroyed. In the end, Changde actually listened to Xiaotian, went down the mountain to help the enemy, and captured Li Suzhen alive. Li remained unyielding under torture and was secretly released by Oda's daughter Mieko. Oda was unable to report to his superiors, and angry that his daughter had missed a military flight, Mieko was handed over to the headquarters pretending to be Li Suzhen. Amu was inhumane, ruined Mieko and then killed her. Oda was filled with regret and committed suicide at the ceremony. Under the guidance of our underground party, more than fifty girls from the Chia Women Club defected to the Baiyangdian Anti-Japanese Base Area
