Sediq

The Yunhai Tai-Power Hut in Renai Township, Nantou County, is located 4.5 km away from the Nenggao Traversing Historic Trail. The building was formerly the Weishan Police Post built by the Governor-General in Taiwan in 1931. Later, it was burnt down during the Wushe Incident, and rebuilt again on the southern ridge of Mount Weishan at an altitude of 2,386 meters.

In terms of topography and space, the Yunhai Tai-Power Hut is on a wide and flat land with a good panorama. There are often seas of clouds in summer and autumn, hence the name Yunhai (sea of clouds). In the post-war period, the building was refurbished several times by Taipower, but only the interior and so the appearance remained roughly the same as during the Japanese occupation. The open space in front of the hut is currently where climbers rest or camp.

The Nenggao Traversing Historic Trail in Renai Township, Nantou County used to be a road for the Sediq people to hunt and travel.

In the Taroko War in 1914, this road was also used by the Government-General in Taiwan to send troops to attack the Turuku people. Afterwards, for the sake of long-term stability, the Chuying to Qilai crossroad was excavated along the existing old Nenggao Trail. However, due to the high elevation of the east section of the trail and that it was difficult to pass during winter, the whole trail was rebuilt in the middle of the Japanese Occupation period.

In the early post-war period, the Nationalist Government erected iron towers along the Nenggao Traversing Historic Trail as a protection route for power transmission from east to west. Nowadays, hiking from the Tunyuan entrance of the Nenggao Traversing Historic Trail has become a popular hiking route.
