The "Community Inspection Ambassador" of St. Joseph's Catholic Primary School in Jordan Valley discovered that most of the streets, housing estates and public facilities near the school are named after the words "cai" and "stone", which originally originated from the history of the area as a quarry. Through personal inspections and street interviews, the ambassadors seemed to have walked into a time tunnel and realized the changes in the community over the past century. Finally, they designed the "Colorful Fun Tour of Jordan Valley" travel app to allow people from inside and outside the district to explore the community together.
