The eastern coast of Taiwan is home to many prehistoric cultural sites, most of which belong to the Kirin Culture of the late Neolithic period, dating back about 3,500 years. The Kirin Culture is also known as the "Megalithic Culture," a name derived from the numerous large single stones and stone coffins discovered at excavation sites. The Chang Guang Site is one such remnant of the Kirin Culture. Some sites along the eastern coast are too close to local settlements, leading to accidental destruction by residents in the past, prior to awareness of these prehistoric artifacts; this has made excavation and preservation difficult, with many sites now unrecognizable, which is a great shame. The Chang Guang Site is a notably intriguing place, as the area is now part of a residential community, yet excavated artifacts have ingeniously integrated into it, forming an unusual phenomenon of "a site within the community." In the "Shi Keng Cultural and Historical Museum" in this community, excavated broken ceramic shards are presented with artistic decorations in their original shapes, presenting a brand new appearance. Stone coffins, mostly located within private residences, are represented in a replica at the National Museum of Prehistory in Taiwan. In addition, a stone monolith with a shouldered feature, unearthed as a prehistoric remnant, stands by the roadside in a certain location within the community, enveloping the whole neighborhood in a prehistoric cultural ambiance.
