The Residence of Scholar Wu, located in Shangku Village, includes two parts of houses, two Hu-Long houses (a kind of attached building), and an openair courtyard in front of the residence. It is the largest ancient residence in Liehyu Township. The founder, Wu Ching-shan, got rich by running the shipping and saltrelated business. In 1840, he built a study to promote the general education in his hometown. Later on, the study was used by Wu Wen-chang, a scholar in the Ching dynasty, as a residence. Therefore, it was called "Residence of Scholar" by the locals. The Residence of Scholar Wu includes two parts of houses and two Hu- Long houses. The front house as well as the two Hu-Long houses is walled and thus an
open-air courtyard is formed between the front house and the wall. The wall is built with different materials. For example, the bottom part of the wall is made of stone, and the part in between is made of brick. The residence is equipped with two kinds of roofs, including raised-ridge and horseback-ridged roofs. There are three semicylindrical tiles on either side of the raised-ridge roofs. The inscription "Hua Kai Fu Kui" is framed by swallow-tailed brick on the top of Wankuangmen. The window lattices of the Hu-Long houses are also delicately carved. The construction of the residence is in the form of "Ying Shan Ke Lin'' (a kind of load-bearing wall). The front rooms are equipped with rolling-canopied roofs. There are four crossbeams piled up under the roofs. The residence especially features its wood carvings. There
are two phoenix carvings placed on the beam of the front house, which is rarely seen elsewhere. In addition, four pieces of wood carvings are used as a wall in front of the main hall of the rear house. Each piece of the wood wall is carved with an image of dragons and auspicious flowers. Various clay sculptures can be found on the roofs of the two houses. All of these deserve a close and careful look.
