Puyi himself complained that he had issued so many "slavish" pro-Japanese statements during the war that nobody on the Allied side would take him in if he did escape from Manchukuo. In June 1942, Puyi made a rare visit outside of the Salt Tax Palace when he conferred with the graduating class at the Manchukuo Military Academy, and awarded the star student Takagi Masao a gold watch for his outstanding performance; despite his Japanese name, the star student was actually Korean and under his original Korean name of Park Chung-hee became the dictator of South Korea in 1961. In August 1942, Puyi's concubine Tan Yuling fell ill and died after being treated by the same Japanese doctors who murdered Wanrong's baby. Puyi testified at the Tokyo war crimes trial of his belief that she was murdered. Puyi kept a lock of Tan's hair and her nail clippings for the rest of his life as he expressed much sadness over her loss. He refused to take a Japanese concubine to replace Tan and, in 1943, took a Chinese concubine, Li Yuqin, the 16 year-old daughter of a waiter. Puyi liked Li, but his main interest continued to be his pageboys, as he later wrote: ""These actions of mine go to show how cruel, mad, violent and unstable I was"."
