I want to learn how to learn Feng Shui.

I suggest you start by understanding what Feng Shui is, at least have a basic understanding of Feng Shui, and then learn some basic concepts. There are many terms in geomantic omen, and the concepts are complex and easy to remember. Case study is recommended. Many people will recommend you all kinds of introductory books. Actually, it's better to find a teacher who relies on music. Teacher Hou Zongyuan's study class is good and can be downloaded from Baidu.
