You only need birthdates to set up a Feng Shui array?

Take it easy, the landlord. It's great that Feng Shui is so simple. Knowing a person's name, birthdates, address and these ID cards can be inferred. It's very simple and it's impossible to be effective.

If you want to use magic, you must wear your own clothes, shoes, hair, blood, etc. to have a chance, and it may not be effective. For example, if someone else's protector is powerful, your magic is useless.
