What is the length and area of the house to meet the scale of Luban?

The written description of architectural law is difficult to understand. You must first correctly understand the basic usage of Lu Banchi.

Luban size: Lu Banchi's standard size is 46 cm, and the allowable deviation is 0.5 cm. The popular Lubanchi is not accurate! -Verification of Lu Half-foot Standard Size (Li Shouli) Confucius said: "If you want to do a good job, you must first sharpen your tools." To learn geography and geomantic omen, you need an accurate compass and Lu Banchi, but the popular Lu Banchi is not accurate. This kind of Lu Banchi was first produced by a company in Shanghai. Later, various manufacturers followed suit, and the format of steel tape measure was wrong. It uses a 42.9 cm Lu Banchi, which is inaccurate, and a 50.4 cm Lu Banchi, which is inaccurate.

Lu Banchi and Ding Lan Chi only play an auxiliary role in the geomantic operation of Yin and Yang Rooms. For example, in terms of the scale of the works, Lu Banchi and Ding Lan's ruler are not very effective. In the geomantic art of Yin and Yang's family, only dragons, caves, sand, water and directions are put away, and you will make a fortune without the ruler of Lu and Ding Lan. Of course, you can still measure the length of the desk and office door in your spare time. When you use the Lu Banchi and Ding Lan ruler, you are sitting in the direction of the yin and yang room.
