The Jeong Jae-su Memorial for Filial Piety was constructed to honor the bravery of Jeong Jae-su who died at the age of 10 trying to rescue his father. It was opened on June 12, 2001 at the former Sasan Elementary School where Jeong was a student. In the Jeong Jae-su Exhibition Room on the first floor, materials relating to Jeong’s filial piety are on display. In the Filial Piety Exhibition Room on the second floor, various materials on general filial piety and works created by students are on display. The theater shows movies on filial piety, including one about Jeong’s virtuous deeds. The theater is also used for seminars and conferences on filial piety. There is also an outdoor performance stage, a facility for traditional folk games, and a rest area.
