Chinese Tea Mythology: Monkey Picked Tea

I first came a crossed the Monkey Picked Tea while in search for good cream tea. I had never heard of it before but the name intrigued me as did the description of its fruity flavor. It is an oolong tea known for its orchid aroma. I was given a pot of this intriguing tea along with my scone, clotted cream and jam. I was immediately hooked but I had one nagging question: why was it called Monkey Picked Tea?
