Huangji Village in Xingning, Guangdong, is known for its Tongshu Luo houses

The Tongshu Luo house, a two-hall, four-wing, three-enclosure dragon house, is located in Huangji Village, Fuxing Sub-district, Xingning City, Guangdong Province. It was primarily built by Luo Fayang, the son of Luo Qinghui, the founder of 'Luo Family Tongshu', during the Kangxi period of the Qing Dynasty. The Tongshu Luo house covers an area of about 4,600 square meters, with a construction area of 3,351 square meters. Facing south with its back to the north, it features two halls, four wings, and three enclosures forming a dragon house, with a grain terrace and a pond in front. There are 4 halls, 99 rooms, and 1 courtyard, with 4 wooden columns in the upper and lower halls. The wall foundation is made of rammed earth, while the upper part is constructed of earth bricks, wood, and tiles, with a hard mountain roof. This residence is a typical Hakka dwelling in Xingning. On August 10, 2009, the Tongshu Luo house was announced by the Xingning Municipal People's Government as a 'Xingning City Featured Ancient Dwelling' protection unit. The Tongshu Luo house possesses the Xingning Luo Family's Tongshu calculation method, which was first created by Luo Qinghui in the second year of the Yongzheng period (1724) of the Qing Dynasty. It holds an important position in China and plays a significant role in guiding people's production and life. The 'Luo Family Tongshu' calculated using this method was once granted imperial permission by the Yongzheng Emperor to be published and distributed in the five provinces of South China. Its content is rich and precise, mainly including lunar phases, head origins, mountain lessons, and marriage matters. It contains aphorisms, detailed explanations, practical examples, and uses a 39-bead abacus for calculation, offering meticulous and profound guidance that is convenient and practical.
