zuoqing

Literal meaning

make/work + green (leaf)

Definition#

The defining oolong step: alternating rounds of shaking or tumbling (摇青) and resting (晾青) over many hours. Bruising the leaf edges triggers enzymatic oxidation at the margins while the leaf 'breathes out' moisture (走水), producing the 'green leaf with red edge' look and the aroma. The heritage text stresses 'judging the leaf' (看青做青) and 'judging the weather' (看天做青).
