Names and ambiguities#

Selection or mutant?

TRES says Muzha farmers selected it; a National Chung Hsing University release calls it a local Muzha mutant. Neither calls it a chance seedling, and no discoverer is named in an official source.

12

Notes#

In Mingjian it gives the earliest spring and latest winter (冬片) crops, six to seven a year. With TTES 12 it is now the main cultivar there, having displaced part of TTES 13 (TRES). It is the third most planted cultivar in Taiwan (MOA).

Teas made from it#

Grouping for Taiwan's partly oxidised teas, from strip Baozhong (about 8–25% oxidation per TRES) to Oriental Beauty (50–60%), mostly from Qingxin Wulong and Jinxuan.
