The Monument of the Death of Sergeant Niki Sanjuro of Karenkou Prefecture is located on the side of the ridge valley by the Batongguan Traversing Historic Trail, about 1,770 meters above sea level, on the south side of the first Eshira railway bridge, which is about 10 minutes away from Eshira Police Post.

Originally, there were two pillars erected, one was to commemorate the death of Sergeant Niki and the other for Police Officer Lai Minghe, who were killed by gun ambush in the dense forest on October 23, 1920. They were on duty supervising the second phase of the construction of Batongguan Traversing Historic Trail. Later, it was converted into one reinforced concrete obelisk-shaped monument in the mid-Japanese occupation in the 1930s, but the inscription only bears the name of Niki Sanjuro.

The Monument of the Death of Police Officer Sura and Ansen of Karenkou Prefecture (now Hualien County) is located beside the Batongguan Traversing Historic Trail. It is about 100 meters away from the Sasarabi Police Post, and about 1 km away from Dumas Police Post in the east.

The reinforced concrete obelisk-shaped monument was set up by the Governor-General in Taiwan to commemorate two police officers, Sura and Asen, who were killed in an attack on February 17, 1921. The two officers were ordered to patrol and transport supplies to the Dafeng Police Post, and on return to Dumas Police Post in the afternoon, they were killed while patrolling nearby.

Maiasang Police Post is located in the valley beside Batongguan Traversing Historic Trail on the north branch of the southeastern ridge of Mount Nandashuiku, about  2,650 meters above sea level. It was built in 1920 and the name Maiasang means ancestral home in the Bunun language. Maiasan Police Post situated in an alpine climate, mostly shrouded in white fog. The snowfall period is between November and February. At times when there was heavy snowfall, the guards at Daishuiku Police Post, which is stationed several kilometers away, will retreat to Maiasang Police Post, where there is a ravine water source nearby.

Today, the foundation where Maiasang Police Post was stationed is overgrown with Taiwan red pine, and only a few building structures and relics remain.

Dashuiku Pond is a high mountain pond that does not dry up all year round. It is located on the eastern section of the Batongguan Traversing Historic Trail, which was built in the Qing Dynasty period. The water source depends on rainfall and snowmelt. The Bunun people refer to the pond as Oniyap, which means pool. Since the Qing period, this area has always been a traffic hub. Dashuiku Pond was an important drinking water source on the main edge of the Central Mountain Range that provided daily water for the Dashuiku Camp. The water source, as recorded in the "Taiwan Map '' compiled at the end of the Qing Dynasty period or "Taiwan General History'', referred to Dashuiku pond.

Today, a large number of ceramic fragments from the Dehua kiln in Fujian from the Qing period can still be found behind the house in Dashuiku.

The Batongguan campsite built during the Qing period and the Batongguan Police Post set up during the Japanese occupation are not on the same foundation. The two are 120 meters apart, and the altitude is about 2,745 meters. The origin of the place name “Batongguan” is the transliteration of Pantonukua, which Tsou people refer Yushan (Mount Jade) to. At present, there are still two bases surrounded by rammed earthen walls at the Batongguan campsite from the Qing period.

The Batongguan (Pattonkuan) Police Post is located on the vast Batongguan grassland between the Yushan Mountain Range and the Central Mountain Range. It is the junction for Batongguan Traversing Historic Trail from the Japanese era and Xingkao Mountain Trail. Due to the dangerous terrain and excellent outlook, the Governor-General in Taiwan set up a police post there, as well as facilities such as trenches, shooting ranges, and observation decks. Every autumn, a wrestling contest was also held here for every police post on the Batongguan Trail. As a result, the Batongguan Police Post became the best reception place, with spacious and comfortable premises. To this day, telephone line obstructions and life relics can still be found on the site.
