Born in Fuzhou, he was educated at the local naval academy and was sent to Britain for further studies. Lin rose to become an admiral in the Beiyang fleet during the Qing dynasty and continued to serve in the Republic. In 1917, reacting against Duan Qirui's dominance over the Beiyang government, he defected with his ships to Sun Yat-sen's rival Constitutional Protection government in South China. For his actions, he was made a member of the governing committee and navy minister. Soon a split emerged within the committee with him siding with the Old Guangxi clique against Sun. Sun's forces, led by Chen Jiongming, defeated him and his Guangxi allies in 1920.
