New house layout? The tomb of an old man or ancestor? The company has opened? Or what?
You have a clear goal.
Generally, we show geomantic omen to new houses in five hundred to several hundred thousand directions. Most of them are one or two thousand. If it's just a general look at 500 is enough. If there is a problem, it will be expensive.
The old man's tomb depends on the arrangement of distance and time.
It's not cheap anyway.
If it's just a kind of peace of mind, the Eight Immortals Temple. There are many places like Guangren Temple and Jionji. Find a person with moral character and kickbacks.
