Abstract: What's the difference between Lu Banchi and ordinary rulers and tape measures? Half a foot of Lu can not only measure the distance, but also the eight characters of Feng Shui, and even better measure the good and bad luck of Yin and Yang. Ordinary rulers are only used to measure length. Tape measure is a common measuring tool in daily life. We often see steel tape measures, which are often used in construction and decoration. Lu Banchi, Feng Shui ruler and secretary also belong to steel tape measure. First, the difference between Lubanchi and ordinary rulers

Lubanchi also made a "ruler-like ruler" as a measuring tool for building a house. Later, eight characters were added to the geomantic circle to measure the quality of the house, which was called "door meter" or "square ruler". Ordinary rulers are only used to measure length.

The traditional Lu Banchi is mainly divided into two parts: the upper part is called the door ruler and the lower part is called the Ding Lan ruler.

1, the household meter is used for building houses and measuring residential houses and electrical appliances. There are eight words on it: wealth, illness, divorce, righteousness, official, robbery, harm and happiness. Eight words are a cycle, and the length of a cycle is one foot two inches and eight and a half, which is about 43 centimeters according to the current size. The official is rich and righteous, and the illness robs the murderer. Each inch is divided into four cells, each cell has four layers of meaning, and each layer is divided into good and bad, and is marked with red and black, with red indicating good or bad.

2.' Ding Lan ruler', also called' Yin ruler', is a bent ruler (ten inches) with a length of one foot, one inch and eight minutes. It is mainly used to measure and judge good or bad luck when building tombs or placing ancestral tablets and gods.

Second, the difference between Lu Banchi and tape measure.

Lu Banchi, also known as class ruler, door ruler, door light ruler and eight-character ruler. The length of the ruler is 1.44, and the unit of measurement is feet. Combination ruler is also called tape measure, and the unit of measurement is centimeter. The standard size of Lu Banchi is 46 cm, and the allowable deviation is 0.5 cm. There is a Lu Banchi in the Palace Museum in Beijing, which is 46 cm long, 5.5 cm wide and 1.35 cm thick.
