Lucky numbers from 4 meters to 5 meters

The length and width of the house are numbered in 'steps',

(there are three steps around 5 meters); the specific auspicious numbers are: 401, 402, 407, 408, 409, 418, 419, 420, 421, 422, 423, 424, 425, 466, 467 (the above values ​​are in centimeters). The correct total length of the 'Luban ruler' is exactly 32.cm (±5 mm). A building ruler (that is, a carpenter's ruler is calculated as 1 foot) takes 5 feet as a step. In the construction method, take the last step. The value is based on the method of 'not doing all the steps', and only 4.5 feet is used as the construction rule, rather than all steps being calculated based on 4.5 feet. (There is such a ruler in the Shanghai Museum, and the "China Wan'an Feng Shui Ruler" is also a copy of this original size) This is the legendary folk construction ruler, and it is also the "Luban Ruler". Other forms of ‘Luban Ruler’ are all rumored. The "Luban Ruler" that describes consecration, suppressing evil spirits and using the ruler to bring good luck and avoid evil can only be used as handicrafts for fun. Do not use it seriously, otherwise it will be counterproductive! Regardless of whether the length of the "Luban ruler" is 42, 43, 45, 46, 50, 52 centimeters, etc., first of all, regardless of the classification of good or bad luck, just looking at the total length of one foot is enough to understand whether it is practical.
