The "Qiu Hui collection" (秋惠文庫) primarily consists of ancient documents from the Qing Dynasty and Japanese Colonial Period, spanning from the 31st year of the Qianlong Emperor (1766) to the 36th year of the Meiji Era (1903). It includes official correspondence documents between the Anli (岸裡社) and Maoluo (貓羅社) tribes and the authorities. There are also land lease agreements from Jiaoxi and Toucheng in Yilan, involving transactions with communities such as the Chiwulan (淇武蘭 社) and Qiwulao (奇武荖社) tribes.

Additionally, the collection features Sinkang Manuscripts during the Qianlong period, educational records from the Jiaqing period, and maps of Taipei City Wall during Qing Dynasty. Documents related to the construction of Yunlin County in and land reclamation in central Taiwan are also included. These encompass cultural records like Chen Shile's "Eight Views of Yunlin" and resume-related documents for Chen Shangda, alongside maps of Nantou and Yunlin County.

The catalog of these archival documents is now accessible through the "Taiwan Archival Information System," where visitors are welcome to inquire and access digital images in person at the archives.
