Mareppa Police Post is located inside the Xinwangyang Cemetery in Ren'ai Township, Nantou County, on the 29 km point of the Lixing Industrial Road, at an altitude of about 1,500 meters.
Xinwangyang Cemetery was originally the Wangyang village, also known as Mariba or Mareba. The people got relocated to settle here during the Japanese occupation. In the post-war period, due to landslides and stress about the safety of residence, the village was collectively moved to a place with relatively stable ground in the southwest and named Xinwangyang.
Nowadays, most of the tribal people are engaged in non-tropical and high-mountain agricultural work, which is an important source of local income.
