We passed the famous Zhushan Lookout, a popular spot for witnessing the sunrise over Yushan. Since this location attracts many visitors in the early morning, be prepared to see a crowd of eager heads awaiting the sun's first rays.

About Mt. Data (Tashan) and Mt. Xiaota

Mt. Data, also known as Tashan, is the highest peak in the Alishan Mountain Range. It, along with the nearby Mt. Xiaota (Little Tower Mountain), is considered sacred by the indigenous Tsou (Cou) people, who have lived in the Alishan region for generations.
According to the beliefs of the Tsao people, Tashan is a realm belonging to the Gods, which is why they regard it as a sacred site. They believe that the spirits of good people ascend to Tashan after death, while the spirits of those who were not good go to Mt. Xiaota.

The highest mountain on the right is Mt. Data.
In the past, the Ministry of National Defense in Taiwan established a transmitter station at the peak of Mt. Data for rescue operations and stationed guards there. A trail was constructed to facilitate the maintenance and supply of materials for the station.
After the station was decommissioned in July 1998, the area gradually returned to nature. However, in 2002, the Forestry Bureau decided to transform the site into a hiking trail, making it accessible to the public.
