Over an extended period, interactions among people inhabiting a certain land and that which they pass down from generation to generation accumulate to form a profound culture embodied by folk customs that later generations can observe through tangible and intangible heritage. In particular, intangible cultural heritage, such as festivals and rituals, might slowly disappear as lifestyles change. In such cases, artists’ creations are necessary for preserving collective memories. 

Artists explore tangible heritage, such as architecture, from different perspectives, describing it through the use of various techniques, and interpreting its beauty. Intriguingly, the swallowtail roof is a common feature of the Spring and Autumn Pavilions in Kaohsiung, Dacheng Hall of the Confucius Temple in Tainan, and the Lin Family Mansion and Garden in Wufeng, Taichung. This roof style was popular in southern China in the early 20th century. Its appearance in paintings reflects the aesthetics of the time, emphasizing the idea of preserving the past through art.
