Kenji Doihara
Liu's wife was an agent working for Kenji Doihara, bringing many confidential documents with her on defecting to the Japanese. After this, Liu himself was forced to become a fugitive to escape Dai Li's secret police. After becoming a monk and spending years in Guizhou, Chiang's men found him by chance. Chiang showed leniency by offering Liu a position as vice-speaker of the KMT Congress. When he went to Taiwan, Liu lived in poverty, and before his death in the 1960s his last contribution was to provide valuable details for an article on the BSS written by an American professor.
