In late 2009, CCTV, China's State television has made a series of 5 documentaries on Wu Yi tea. And they even translated them into English! They show the wonderful landscapes in which the best rock teas grow. There is also quite a lot of historical and cultural information. The majority of the information is good, but some of is not. Also, at times it sounds more like propaganda (or advertising) than a documentary. There's a lot to criticize, but I did find it very interesting to watch, if only just for the beauty of these sacred mountains, the origin of both red tea and Oolong tea:
Description of Wu Yi tea's characteristics
Wu Yi's early tea history, trade with Russia.
Lapsang Souchong. Wu Yi's red tea and its impact on the the Western world
Royal Tea gift, Jian bowl, tea competition.
All about Da Hung Pao
In Part 3, the documentary mentions Robert Fortune, the Scottish botanist who stole/acquired Chinese tea plants and seeds and introduced them in India in the middle of the 19th Century. If you want to study this story in more detail, I recommend his (free, online) book "A journey to the tea countries of China, including Song-Lo and the Bohea hills". His description of Woo-e-shan in Chapter XIII shows his amazement: " I had expected to see a wonderful sight when I reached this place, but I must confess the scene far surpassed any ideas I had formed respecting it."
