Zhengyan is a mapped 70-square-kilometer zone the law does not protect
Zhengyan is a mapped 70-square-kilometer zone inside the Wuyi Mountain reserve, not a marketing word, but China's national standard for Wuyi rock tea protects the whole administrative city instead, leaving the boundary that commands the real price premium enforced by nothing but reputation.
Oolong and Geographical Indication
A protected name is not a quality grade. What geographical-indication protection actually certifies for Wuyi yancha, Anxi Tieguanyin, and Phoenix Dancong, why Taiwan's oolongs sit outside that system entirely, and why an American shop can sell fake "Tieguanyin" legally, not because no protection exists, but because none of the four names has ever filed for the one the US offers.
The History of Oolong
Oolong was not invented once. Two Fujian counties still dispute the original break from green tea, Guangdong's Phoenix mountains claim a separate and older founding legend, Taiwan received the method by migration a century later, and the word "oolong" itself only reached print in the 1850s. The documented record, region by region.
Oolong and the National Standard
A bag of oolong answers to a real government document before it answers to a taster, and the document is not one standard but a system: a mandatory floor, a recommended ceiling, and a technical committee of tea professionals who write both.

Yancha, Wuyi Rock Tea
Yancha is the oxidized, charcoal-fired oolong of the Wuyi cliffs, defined by the mineral yan yun and sorted by the state into five official categories. The canonical account of what it is, how it is classified and graded, how it is made, and the documented history from Tang-dynasty tribute leaf to today's regulation.
