Pink Shoe

This morning just before it was time for church two young Mongolian ladies knocked on our door.  They announced they were with the 'Pink Shoe' Union.  I had to confess that "pink shoe" was a word that hadn't made it into my vocabulary yet.  So they explained how it wasn't really a religion, but had to do with creating and using good energy for a healthy and life known as Ping Shu.  Mongolians frequently switch the pronunciation of F and P.  So I was finally able to gather that this was some kind of Chinese Mysticism that it seemed like I'd heard of before: Fing Shu.
