Aihe was originally a canal for transporting timber during the Japanese colonial period. Although it was named after the martyrs, it is now a place where couples show great love. Riverside parks have been built along the lower reaches of the Aihe River. Dragon Boat Festival, dragon boat rowing and major festivals or activities are held here every year. In addition, besides the romantic riverside style, there are also many berths along the river for tourists to take the boat of love to view the beautiful riverside scenery.
