Lin was a middle son of Duke Huan of Chen, whose brother Chen Tuo murdered Lin's eldest brother Crown Prince Mian and usurped the throne in 707 BC. The army of the neighbouring State of Cai killed Chen Tuo in 706 BC and installed Duke Li of Chen, another brother of Lin, on the throne.
In 698 BC, Chen joined the armies of Song, Qi, Cai, and Wey to attack the State of Zheng. Song led the attack, to avenge an earlier attack on Song by Zheng. The allied forces burned the Qu gate of the Zheng capital and entered the city. In 697 and 696 BC, Chen and other states attacked Zheng two more times.
