Start with the structure
Flying Star Feng Shui (Xuan Kong Fei Xing) is a time-and-space system. It assigns nine stars to the nine sectors of a building based on its facing direction and the 20-year period in which it was built, then flies them forward each year and month.
Then read the interaction
You read a Flying Star chart by overlaying the nine-square grid on your floor plan, aligned to the true compass facing, then judging which activities each sector supports. Bedrooms want good mountain stars; a wealth star at the door welcomes income.
Put it to use
The annual stars change each Lunar New Year. Knowing where this year's 5 Yellow and 2 Black land tells you which corners to keep quiet and which to activate — a yearly tune-up rather than a one-time fix.
Try it yourself: Flying Stars (Xuan Kong) is free on FengMaster, computed to the letter.
