Shetou is the hometown of the hosiery; however, "Qingshuiyan Ecological Display Center" collects abundant and precious insect specimens. It would become an important location for ecological tourism along Bagua Mountains. The Qingshuiyan Ecological Display Center was founded by the Tri-Mountain National Scenic Area Headquarters of Tourism Administration, MOTC; Changhua County Government; and Shetou Township Office. There are hundreds of precious insect
specimens collected in this center, and Hung Chih Chang, a retired teacher, has
donated almost one thousand of his collections of specimens to the center for
permanent display, and in turn allowed for the preservation of a complete
collection for ecological conservation education in Bagua Mountains.
