=== [[Teh pascafermentasi]] ===
Teas that undergo a second oxidation, such as [[Pu-erh tea|Pu-erh]], [[Liu'an tea|Liu'an]], and [[Liubao tea|Liubao]], are collectively referred to as secondary or post-fermentation teas in English. In Chinese they are categorized as ''Dark tea'' or ''black tea''. This is not to be confused with the English term ''Black tea'', known in Chinese as red tea. Pu-erh, also known as Póu léi (Polee) in [[Yue Chinese|Cantonese]] is the most common type of post-fermetation tea in the market.
