In the first year of the Republic of China (1912), the Qing Dynasty fell. Shanqi wanted to restore the country with the help of Japan, so he gave his daughter Xianyu to Kawashima Naniwa as his adopted daughter. Xianju then changed her name to Yoshiko Kawashima and was sent to Japan to receive militarism education. When she became an adult, she returned to China and worked as a spy for Japan for a long time. In the 16th year of the Republic of China, she married Kangyurzabu, the son of the Mongolian bandit Babuzabu, which was actually a means of political aggression against Inner Mongolia. Seventeen years ago in the Republic of China, he went to Shanghai to engage in espionage activities. He has successively held important positions such as "Commander-in-Chief of the Anguo Army" and "Commander-in-Chief of the North China People's Self-Defense Force" in the puppet Manchukuo. He has participated in secret military operations such as the Huanggutun Incident, the September 18th Incident, and the Manchurian Independence Movement.
Japan surrendered in 1945. On March 25, 1948, Yoshiko Kawashima was sentenced to death for being a traitor and executed by firing squad in Peking No. 1 Prison. She was 41 years old.
