Oolong and Jin Xuan

They always use plain oolong to refer to the lower quality teas. For example In Anxi their oolong is divided up into three categories: Tieguanyin, Sezhong (Which is many different varietals) and Oolong. In my opinion they probably do this either because it is so cheap that the precessing style, the varietal and the origin are irrelevant (In general people drinking these teas may not know enough to find this information useful), or because they are a blend of a few different things, and it might confuse customers rather than make things more clear.

Often in China I get condescending looks from certain people when I say I like Taiwan oolong. I think this is because they assume I drink the tea which is only marked as oonlong from Taiwan, when what I mean is I like a variety of Taiwan oolongs. In Taiwan when they want to make a regular oolong sound fancy without adding a varietal or place name which could be construed as deliberate lying they just call it high mountain oolong.
