Shows you do not know much about feng shui, this is coming from a novice like me.
Sure you have heard about the Luo Pan, there are many types and some has to be read in conjunction with the person's 8 characters. without knowing your birthdate, how can the feng shui master even tell whether you are earth, wood, fire or water? The San Yuan method below is a common method employed by fengshui masters who see people's homes. The stars change with the years and it is not fixed.
Since the Ming and Qing dynasties, three types of luopan have been popular. They have some formula rings in common, such as the 24 directions and the early and later heaven arrangements.
San He
This luopan was said to have been used in the Tang dynasty.The San He contains three basic 24-direction rings. Each ring relates to a different method and formula. (The techniques grouped under the name "Three Harmonies" are San He methods.)
[edit]
San Yuan
This luopan, also known as the jiang pan (after Jiang Da Hong) or the Yi Pan (because of the presence of I Ching trigrams) incorporates many formulas used in San Yuan (Three Cycles). It contains one 24-direction ring, known as the Earth Plate Correct Needle, the ring for the 64 trigrams, and others. (The techniques grouped under the name "Flying Stars" are an example of San Yuan methods.)
Zong He
This luopan combines rings from the San He and San Yuan. It contains three 24-direction rings and the 64 trigrams ring.
Other Types
Each Feng Shui master may design a luopan to suit preference and to offer students. Some designs incorporate the gua (trigram) numbers, directions from the Eight Mansions (ba zhai) methods, and English equivalents.
