In 1855, a Taiwanese man named Lin Fengchi brought 36 Qingxin Oolong tea seedlings from Fujian, China. Twelve of these seedlings were planted on Dong Ding Mountain in Lugu Township, Nantou County, and they thrived remarkably well. Over the next hundred years, local tea producers gradually developed unique tea-making techniques, forming the foundation of modern Dong Ding Oolong Tea.
