Ruisui Township has indigenous ethnic groups such as the Amis, Sakizaya, and Bunun, accounting for nearly 40% of the township. There are 17 tribes distributed in the villages of Ruisui Township. Activities, under the principle of respecting the subjectivity of the tribes, the leaders of each tribe will decide the time and theme of the joint harvest season by consensus in the affairs team leader meeting, so as to avoid the time when each tribe holds its own harvest festival or year-old festival every year. On May 12, the eve of Mother's Day, the 107 Ruisui Harvest Season - KADUFAHAY and Traditional Skills Competition was held in the playground of Ruisui Elementary School.
