Who was Lu Wu? What were his beliefs about tea?

In the 8th century, a man named Lu Wu was born who could be considered "our first apostle of tea." He combined teaism with Confucianism, Taoism, and Buddhism, producing a book called Ch'a Ching which is considered the Code of Tea. Lu Wu, in this book, describes all aspects of tea - gathering the right leaves, having the right equipment or tea-equipage, making tea, etc. He was very specific in many respects. He insists on mountain spring water as the best tea to brew with, and he prefers blue tea-cups, so they could contrast the best with the green color of the tea. Ch'a Ching also discusses well-known tea drinkers from history, and "vulgar" methods of tea drinking which are to be avoided. Lu Wu is associated wit the Boiled Tea era.
