Hi, I am a chinese ,i know that "Gong Fu" is a real thing,may be you have read many books and watched the film on these .In China there is a place named Shao lin temple where many people practise this ..... you can find it more at http://2008.chinashaolin.org:8080/.

this question is too complex to answer competely.Feng Shui is depend on a kind of philosophy.There is a book about this named Yi Jing.But there are a part of superstition in Feng Shui. Kong Fu in china like taekwondo in Korea.It's a sport much more than art.Even though we sometimes performance.In fact taekwondo is always used in performance.And the Kong Fu in monie is not ture. you can copy 风水 and 功夫 to baidu.And you will find much info.But most of them are Chinese and a little hard to understand. I wish my poor english didn't make much misunderstanding

Feng Shui may be related to taoism. To seek harmony with nature is the soul of taoism. And there are other kinds of thoughts about taosim. Taosim plays a very important part in Chinese trational culture, together with Confucianism and Buddhism.

I think it is superstition. I dont believe it .
