East Side of the Batongguan Historical Trail
The survey’s first stage, which included the west part of the trail from Jhushan to Dashuiku, was already completed in August 1987. The survey of the east part of the trail began in September 1987, and continued for a year. It included collection of literature, documents, and actual surveying of the trail from Dashuiku to Yuli, a distance which stretched 63.63 km. Apart from differentiating between the Batongguan Historical Trail from the Qing Dynasty and the Japanese-era Batongguan Traversing Road, the study also looked at the Qing Dynasty’s management of eastern Taiwan after the opening of the old trail, the story of the building of the Batongguan Traversing Road during the Japanese occupation, the migration of the Bunun tribe in this area, the rebellion against the Japanese. Individual chapters are devoted to these topics.

 West Side of the Batongguan Historical Trail
Batongguan Historical Trail was listed as one of the first grade national historical landmarks by the Ministry of the Interior. On January 1 of the same year, Yushan National Park Headquarters asked Yan Nan-jiunn to conduct a survey of the Batongguan Historical Trail. The main section of the Batongguan Historical Trail runs from Linpipu (now Jhushan), Fenghuang Hills, Maopu (Aiguo Village, Sinyi Hsiang), Heshui (Heshe), Dongpu, Batongguan, to Dashuiku, and follows the northern bank of the Lakulaku River down to Pushige (Yuli), running a total of 152.64 km. This study had used six months to complete the survey of the 89.28 km stretch of the trail from the west of Dashuiku of the Central Mountain Range to Jhushan. Conditions along the study area had been faithfully recorded and the results showed that 80% of the west part of the Batongguan Historical Trail is still utilizable, with only a few sites where river wash and landslides had occurred needing restoration. With the removal of the profuse trees and dwarf bamboos, the historical trail could be completely cleared for utilization.
