Tang Ju-wu had been the commander of the 1st Regiment of the eastern frontier defence force., that was disbanded and interned by the Japanese during the early days of the invasion of Manchuria.
Tang Juwu escaped and then cut one of his fingers and wrote eight Chinese characters meaning "Kill the enemy, punish the traitors, save our country and love our people."
After escaping internment, the Northeast National Salvation Society appointed Tang as commander and helped him get in touch with smaller forces which others were organising in eastern Liaoning province.
Tang also made use of his extensive personal contacts with police chiefs, officials, local gentry militias and the leaders of the semi-clandestine Big Swords Society.
After the defection of the Manchukuoan 37th Route commander Wang Yongcheng, Tang Juwu was able to break through the Japanese encirclement to the west and escape.
