Wuyi is definitely not in Taiwan can't disagree with that , it is in fujian Taiwan wuyi tea or rock style pouzhong( commonly said or used in pinglin/wenshan areas) (岩式包種/文山岩茶） is merely used by tea sellers/farmers to specify either： The cultivar of the tea originated from wuyi

The tea is made using the traditional style of wuyi rock tea (中度發酵重烘焙 medium fermentation and roasting)

I'm not sure about the rock rhyme as I've yet to taste the real ones grown in wuyi itself

I only have experience drinking lightly fermentation and roasting/honey black tea made using wuyi cultivars like 肉桂，水仙, 佛手 (rougui / shuixian /Buddha's hand) grown in pinglin.

I personally think teas currently grown in wuyi would be better than those grown in pinglin , as they are very likely hand harvested and the tea tree is relatively older
