Flying Star ( Xuan Kong) is the most powerful tool used by most professional Feng Shui practitioners. It has absolutely nothing to do with Astrology. It is an analysis of the five elementts, land formations and star combinations that occupy your building. Each Chinese New Year these annual stars change, bringing good and bad energy. Every building throughout the world will have these changing annual stars and you will need to take account of their ability to cause harm or their ability to bring good luck in wealth, health, romance, education and overall luck throughout the year. Unless a good star is activated it is of no benefit to you and unless you protect your home from the unlucky stars your luck may be affilicted. Use recommended cures or enhancements for the relevant areas to maximise potential good luck and protect your home or busines from harm.
