Part 7 : The Logical Issues of the Zhangzhou Hypothesis
A smaller number of writers propose another possibility: that the technique of qingcha (oolong tea) originated in Zhangzhou. This idea is largely based on the interpretation of a few lines in the poems of Ruan Minxi. But once again the difficulty lies not in the text itself, but in how the text is read. Compared with the Wuyi origin theory, the Zhangzhou hypothesis appears less frequently in tea discussions. When it does appear, however, the structure of the argument often follows a familiar pattern.
The starting point is usually the same group of historical poems. A few lines describing tea production in Fujian are read as evidence that the qingcha technique may have first appeared somewhere outside Wuyishan. From there the interpretation moves outward. Certain geographical references in the poems are sometimes linked to areas that historically belonged to the broader Zhangzhou region. If the tea described in those poems was not produced in Wuyi, the reasoning goes, then the technique itself might have originated elsewhere in southern Fujian.
Seen in isolation, the argument can sound reasonable. Yet the difficulty lies in the nature of the evidence.
The poems themselves are descriptive rather than technical. They mention tea roasting, leaf colour, and the labour involved in tea production. What they do not clearly describe is the defining technique of qingcha processing. That technique is zuoqing (leaf bruising and controlled oxidation). Without an explicit description of this process — the repeated shaking of the leaves, the intervals of rest during which oxidation develops gradually along the leaf edges — the presence of qingcha production cannot be confirmed.
Nor are references to leaf colour such as : ban qing ban hong (half green, half red)
As discussed earlier, such descriptions can appear in several different tea processes. They do not necessarily indicate qingcha production. This is why debates about tea origin often become circular. The same few lines of text are read again and again. One interpretation places the origin in Wuyi. Another moves it toward Zhangzhou. The historical documents themselves remain unchanged. What changes is the meaning later readers ask those lines to carry.
