Dark tea vs black tea
In Chinese, black tea means what English calls dark tea, and English black tea is called red tea. The naming collision causes more confusion than any other in the subject.

What is being compared
Why these get confused
'Black tea' means opposite things in Chinese and English. A Chinese menu offering black tea is offering pu-erh or hei cha, not Assam.
Point by point
| Aspect | Dark tea and pu-erh | Black tea |
|---|---|---|
| What changes the leaf | Microbial fermentation — living organisms acting on the leaf over months or years. | Enzymatic oxidation, driven by the leaf’s own enzymes over hours. |
| Chinese name | Hei cha, literally black tea. | Hong cha, literally red tea. |
| Time involved | Months to decades. | A single afternoon. |
| Flavour | Earthy, woody, sweet and often medicinal. | Malty, fruity or brisk depending on origin. |
| Does it improve with keeping | Yes, and it is often bought for that reason. | No. It fades, and there is no tradition of ageing it. |
The short answer
They are not variations on each other. Oxidation and fermentation are different mechanisms, and the model keeps them in separate fields for exactly that reason.
