What is the "Eight Diagrams Array" dug under the floor of a century-old building in Fujian?

On February 26th, 65438, during the renovation of a century-old antique building in Maxiang Town, Xiang 'an, Xiamen, Fujian Province, it was accidentally discovered that there was a mystery hidden under the floor of the hall, and the "Eight Diagrams Array" was discovered, and the "Brick Deed" written in Chinese calligraphy came in handy. .

According to Mr. Lin, the head of the household, the Eight Diagrams Array is located in the center of the main hall, with a diameter of about 3 meters. In its eight directions, tiles are arranged in a "gossip". There is a "Tai Chi Diagram" in the array, in which each point is inlaid with a copper sheet. At the same time, two "brick deeds" were dug up, one of which was painted with a gossip pattern, and the words "live and work in peace and contentment, grow rich and prosperous, and the descendants of the Golden List will remain young forever" were written in the picture. The general idea is that ancient architecture is a treasure trove of geomantic omen, which has entrusted the good wishes of ancestors and future generations.

Experts in literature and history pointed out that it is very common to dig out "brick deeds" in ancient buildings, which are usually buried underground, with the orientation and structure of the house written on them, but it is the first time to dig out "Eight Diagrams Array" underground.
