AR鲁班尺, also known as "Lu Ban ruler," is a measurement tool traditionally used in architectural design and interior decoration. It consists of four rows, including the traditional Chinese inch, Lu Ban ruler, Ding Lan ruler, and centimeters. The Lu Ban ruler is believed to have been created by Gongshu Ban, a renowned craftsman from the State of Lu during the Spring and Autumn period. Over time, Feng Shui practitioners added eight Chinese characters underneath the ruler, allowing it to be used for measuring the auspiciousness of houses. These eight characters are: "wealth," "illness," "separation," "righteousness," "official," "robbery," "harm," and "essence," each with four sub-characters to differentiate their meanings.
