It’s hardly surprising, given the Wudang Mountains’ special significance to Taoism, that they feature in many legends. One of these legends concerns a mysterious tree, called the betel-plum, which was only found in the Wudang Mountains. The fruit of the tree was even designated as a tribute for the emperor during the Ming Dynasty. Emperor Yongle was so fond of it that he had a hall built in the Wudang Mountains, in honour of the Betel-Plum Deity.
