Early life Born to a middle-class family in Shanggan Township (尚幹鄉), Minhou County (閩侯縣), Fuzhou, Lin was educated by American missionaries. He later worked in the Telegram Bureau of Taipei, Taiwan in 1884. After the First Sino-Japanese War, he engaged in guerrilla activities against the Japanese occupiers. He returned to the mainland and worked in the Shanghai customs office in 1902. He later lived in Hawaii and San Francisco. There he was recruited by the Tongmenghui in 1905, and was an overseas organizer for the Kuomintang. During the Xinhai Revolution, he was in charge of the Jiangxi revolt. He became speaker of the senate in the National Assembly.
