Introduction to Fuzi Building: Fuzi Building is a unique two-story square building with a width of 21.5 meters and a depth of 47 meters. The plan is laid out according to the word "Fu'". The gate of the building faces west, and there are two side gates in the north and south. Across an alley to the east of the building is a row of toilets and warehouses. On the plane, it combines with the surrounding square buildings to form a treasure hijab with the word "rich". Directly opposite the gate in the building is an alley 2.3 meters wide and 27 meters long, which residents call "Sky Street". In the gatehouse at the end of Tianjie, a courtyard is formed by the ancestral hall and the study room surrounding a small patio. From a plan view, this is the "mouth" in the middle of the word "rich". In the middle of Tianjie, four gatehouses face each other across the street. There is a hall with a patio, and their planes form the "field" under the character "富". The outer buildings are connected by the inner corridor, and there are 6 stairs going up and down. The layout of the word "rich" makes the space in the building unique. The couplet "rich families bring good luck, and purple energy comes from the east" illustrates the original intention of the purple building to be laid out according to the word "rich" to pursue wealth and good luck.
