These tea plant varietals are originally from Anxi and are used for Oolong teas of the same name. Some of them, however, are cultivated elsewhere, too:

• Hong Xin Tie Guan Yin (“Red Heart Iron Bodhisattva of Compassion”) is the original Tie Guan Yin varietal. Besides the huge cultivation area in and around Anxi, it is also used in Taiwan, for example in Muzha, Xinbei, where it has been intorduced from Anxi in 1919.
• Rou Gui (“Cinnamon”) originally really comes from Anxi, it has however been cultivated in Wuyishan for a long time now, and most recently in Taiwan, too. The Wuyi Rock Tea named Rou Gui is the most renowned tea from this varietal.
• Huang Dan (“Yellow Daybreak”) and Wu Dan (“Black Daybreak”; a variety stemming from Huang Dan) are used for Huang Jin Gui. Since recently, it is also grown on Taiwan.
• Mei Zhan (having a plum) is being used in Anxi and in Wuyishan to produce simple Oolong. Nowadays it is also made into black and even green teas; this happens in many places, such as the province Sichuan and Fujian.
• Jing Zhi Da Ye Zhong is a cross-breeding between Huang Dan and Mei Zhan, which is used in Fengqing, Yunnan, to craft a black tea (Zhong Guo Hong).
