The Xiaoxi Gate Model Toilet was built in the 6th year of the Republic of China (1917), by Wu Chaoping, who had gone abroad to do business and then returned to his hometown to fund its construction. Wu Chaoping (1854-1936), also known as Guangping (often used in Indonesia and Singapore), was from Xiaoxi Gate. In the 13th year of the Tongzhi era of the Qing Dynasty (1874), he went to Indonesia's Sumatra and, together with friends, established the business "Chengshunfu" in the port city of Asahan (Tanjung Balai Asahan), which was known for its glass production, engaging in the trade of local products. Later, he went to Singapore to do business and actively participated in the public welfare activities in the Nanyang region. In addition to establishing the Peishan School on the island of Sumatra, he was also active in various activities of the Jinmen Association Hall in Singapore. For example, he contributed funds for the reconstruction of the Wuyang Fojie Temple in 1919, and in 1922, he subscribed to a share of 1,000 Straits dollars for the establishment of the Jinmen Steamship Company, which was the largest among the overseas Chinese merchants at that time. He was also once granted the title of Kapitein in Sumatra, Indonesia. In his later years, he lived in Gulangyu, Xiamen. After achieving success in his business, Wu Chaoping returned to his hometown in the 27th year of the Guangxu era of the Qing Dynasty (1900) and planned a group of three two-story houses in Xiaoxi Gate. The buildings were completed in the 29th year of the Guangxu era (1903), the 31st year of the Guangxu era (1905), and the 4th year of the Republic of China (1915), respectively, from right to left. The old toilet pit of the Xiaoxi Gate settlement was originally located in front of Wu Chaoping's newly built houses. Considering the need for a cleaner living environment, Wu Chaoping negotiated with the villagers to move the toilet pit to the southwest area outside the village. Later, Wu Chaoping purchased land and in the 6th year of the Republic of China (1917), built a new "Model Toilet." The Model Toilet was set up with 22 toilet pits according to the original number of households, each numbered. Each toilet consisted of a toilet area and a collection pool. The toilet pits belonging to Wu Chaoping's family were numbered 1 and 2, with roofs providing more private spaces. The remaining 20 open-air toilet pits were assigned by drawing lots, and a contract was established to determine ownership. Each household was allocated one toilet pit, which could be managed and collected by each household for agricultural fertilizer. The Xiaoxi Gate Model Toilet evolved from traditional toilet pits, meeting the needs of public sanitation and agricultural fertilizer in the area. It also reflected the contributions and improvements made by overseas Chinese to environmental sanitation and facility space. (Source: Cultural Affairs Bureau of Kinmen County)
