Feng-Shui Tape Measures – Core77
These are Feng-Shui tape measures.
Known as the rulers of Lu Ban, they were named after a historical Chinese architect/builder who lived during the Zhou Dynasty (nearly 2,500 years ago). What sets these bars apart is that the dimensions that feng shui practitioners believe are auspicious (reflecting Western Golden Ratio proponents) are marked in red.
The thinking is that things must be built or placed in space for these red dimensions. Go with Black Dimensions, well, you’re taking your chances.
