Does anyone know what a Feng Shui ruler looks like? Can you teach me?

Is your question professional? It's just that I'm also interested in Feng Shui these days, and I looked up a lot of information on the Internet. It turns out that the geomantic ruler is also called "Lu Banchi". Lu Banchi has two parts, one is the door ruler and the other is the Ding Lan ruler. The door ruler is also called "Jiu Tian Xuan Nv door ruler" because this part is used to determine the size of the door. Below I will tell you in detail how to look at the Feng Shui ruler, hoping to help you! How to use the geomantic ruler: In Lu Banchi, it is divided into four rows from top to bottom, which are the traditional four kinds of rulers: inch ruler, Lu Banchi ruler, Ding Lan ruler and centimeter ruler. This feng shui ruler is very convenient to use. Many people have this geomantic omen, but they just don't know what it means and how to use it. Here are some related knowledge for your reference. The upper part is meters: used to indicate the size of palaces, shrines and Buddhist instruments. The lower part is Ding Lan ruler, which is mainly used in Yin houses and ancestral temples. The red on the ruler is auspicious, and the black is fierce. Commonly known as Lu Banchi, it is 50.4 cm long. It is divided into eight categories, namely, wealth, illness, separation, righteousness, official, robbery, harm and capital. Wealth, righteousness, official and capital are auspicious, and illness, divorce, robbery and murder are harmful. Each cell is 6.3 cm, and each cell is divided into four cells, and each cell is marked with different good or bad words. The size of Jidu also has different uses. For example, Yimen is mainly used in schools, and closing doors is mainly used in government offices and officials. The words "Ben" and "Cai" are commonly used by ordinary people. Mainly when carpenters make doors, they measure the height, width, threshold and so on. In ancient times, it was emphasized that the dark room in the bright hall and the windows were generally small, so the door was used as the air inlet, regardless of the air intake in the window. Some windows in modern layered houses are larger than doors, but the main entrance and exit doors are not often opened, so we should not only pay attention to the size of doors, but also consider the air intake function of windows (especially floor-to-ceiling windows). For doors and windows that are often opened, the size should be controlled so that the height and width of doors and windows (both refer to clearance) are controlled within the size of Kyrgyzstan. See the table below for the specific meaning of each word. Ding Lan ruler: It is a necessary tool for today's Feng Shui masters. It is mainly used to measure and judge good or bad luck when building tombs or placing ancestral tablets and shrines. Some introductions say that door meters measure doors, and Ding Lan ruler measures furniture. However, the author has measured a lot of old-fashioned furniture, all of which hit the auspicious place of Lubanchi, so everyone should pay special attention in the future. The above is the opinion about Feng Shui ruler for your reference! In fact, people in the industry generally understand that it is difficult for us laymen to understand in a short time! We in China have some feng shui plots. Fengshui has a history of thousands of years in China. Since it can be preserved for thousands of years and passed down, there must be a reason. We might as well accept it with a credible attitude.
