Qixing Zhendi Park was constructed by the Ministry of National Defense; its purpose was to guard the military base of Zhuoshui River and Changhua Plain in the past, for which over 20 military strongpoints and command posts were built in the Songboling region. Since Songboling is situated to the north of Zhuoshui River, the higher ground of Baguashan Cliff provides the best strategic advantage. As a result, the artillery strongpoints undertook the important mission of military defense. Later, the place was no longer required for military purposes and was left idle for many years. In order to develop local tourism, the Mingjian Township Office (Nantou County) entrusted the Tri-Mountain National Scenic Area Administration to renovate the Park with tourist facilities such as lookout, leisure square, footpath and toilets. The township office also borrowed decommissioned tanks and artillery from the Ministry of National Defense to put them on display next to the pillboxes with explanatory information, successfully turning it into a local tourism spot with distinctive features. The name “Qixing Zhendi” was derived from Songboling’s local religious center, Shoutian Temple. The temple’s guardian is Xuanwu, the patron god of the north, and its representative constellations are the Big Dipper and Polaris. Since the location of the seven pillboxes match the pattern of the Big Dipper, the pillboxes are respectively named after the stars in the Big Dipper asterism: Tianshu (Dubhe), Tianxuan (Merak), Tianji (Phecda), Tianquan (Megrez), Yuheng (Alioth), Kaiyang (Mizar), and Yaoguang (Alkaid). Accordingly, the place is named Qixing Zhendi (Seven Stars Battlefield) Park. The pillboxes stand in the midst of green fields, creating a unique scene. You can even climb up to the lookout on top of the pillbox for a rest against the backdrop of Zhuoshui River and Changhua Plain spread with tea plantations, pineapple orchards, and ginger plantations.
