An Jung-geun
Yun headed for Shanghai, judging that he would be able to push for a successful independence movement only if he went directly to the Provisional Government of the Republic of Korea. He travelled alone through Dalian, south of the Liaodong Peninsula, to Qingdao, Shandong Province where he worked at a factory run by Park Jin, a Korean businessman, to save money. In August 1931, he finally arrived in Shanghai and stayed at the home of An Jung-geun in the French quarter. Yun also studied English at the Shanghai English School. He visited Kim Gu (1876-1976), the leader of Korea's government-in-exile pledging to work for the independence of Korea.
