When the
Republic of China ruled the mainland, Zhongguan was known as
Zhongguan Township (钟管乡) until its merger in 1947 into Longxi Township (龙溪乡). In July 1950, Zhongguan Township was re-established and remained a township until October 1958, when it, along with Ganshan Township (干山乡) and Getting Township (戈亭乡), was merged into a people's commune. Township status was restored in January 1984, and Zhongguan was upgraded to a town in April 1989. Getting Township (戈亭乡) was merged into Zhongguan in July 1992, and Ganshan (干山镇) merged in April 2004. == Tourism ==
