Longanpo is an area in the eastern part of the Taipei Basin, near the mountains, which was developed by immigrants from Anxi County, Fujian Province. The Huang ancestors came to Taiwan during the Qianlong period of the Qing Dynasty (1740 AD). Initially, they settled in Tamsui's Fan-shu-liao, and later moved to the Taipei Basin. By the fourth generation, several brothers jointly built a large house, called Lianrangju. Lianrangju was built in the third year after the Japanese occupation, that is, 1897 AD, and the materials used at that time were of high quality.
The house faces south and is surrounded by rice fields. In the middle of the fields stands a red-brick three-hall courtyard house, a typical traditional Taiwanese farmhouse. Its layout is also called "main building with side wings." Originally, there were only two side wings, but later it was slightly expanded, and additional outer side wings were added. The red bricks used may have been made locally in Taiwan, with excellent quality, rich red color, and exquisite craftsmanship. The roof is a double drainage type, with a gently curved ridge, reflecting a simple and practical feeling. The wooden carvings inside the main hall are original from the time of construction, and are beautifully carved. In the century-old traditional farmhouses preserved in Taipei, it has a transitional character from the late Qing Dynasty to the early Japanese occupation period, as can be seen from the materials and decorative features.
