How to study numerology, Feng Shui and five lines of gossip? What books should I read? Where should I start studying?

Feng Shui is very deep, so you can learn the four-column prediction first, and recommend the four-column prediction written by Shao Weihua. This is the foundation. If you feel a little familiar, you can read Yuan Hai Zi Ping and San Tong Ming Hui to learn about Feng Shui. . . It's a little difficult, and it's not practical. As for gossip, I haven't heard of any introductory books, I ching, and it's enough to understand.
