These represent the 4 main traditional areas for oolong production. They're all in a (relatively) compact area.
Fujian province could probably be considered the birthplace of oolong tea, and both Anxi and Wuyishan are areas in Fujian, in the Northern and Southern regions, respectively. Anxi county is where Tieguanyin is from, and the Wuyishan area is where all the hundreds of Wuyi yancha ("rock" or "cliff" tea) are from. There is also tea production in the surrounding areas, as well as in other parts of Fujian. "Phoenix" refers to the Phoenix Mountain (Fenghuan Shan) area in the Chaoshan region of Guangdong province ("Canton"). This part of Guangdong province borders on Fujian, and there are some cultural and linguistic connections between the two areas (the Chaozhou / Teochew language is closely related to the Min languages of Fujian, rather than the languages of most of the rest of Guangdong, i.e., Cantonese).
There are lots of maps online which can give you a better idea visually of this. A few are linked from http://forums.egullet.org/index.php?/to ... geography/
(Shantou is another city in the Chaoshan area).
Without getting into the complex geo-political distinctions, Taiwan has multiple tea producing areas, producing quite a few different types of oolongs from different varietals, though the modern style of gaoshan (high mountain) teas are probably their most popular now. So-called 'Formosa [i.e., Taiwan] oolong' (oriental beauty, dong fang mei ren, etc.) is also very famous. Most of the varietals in Taiwan originally came from Fujian (right across the straight), though there has been some work over there to create new hybrids of these varietals as well.
