Bai Hao means white downy tips, which was present in very large
quantities in Bai Hao Oolong Tea thus its name.

Most oolong teas are made from the second leaf, or the third, seldom
the first unlike this Bai Hao Tea.

Formosan Oolong is known as Bai Hao Oolong at the same time known as
Dong Fang Mei Ren (oriental beauty). Just depends on where you are
from the tea's called differently. Taiwan was known as formosa back
then, and that was how the tea was called formosan oolong.
