Hey, lucky you! More photos please
According to the label, the tea is from Bi Feng, which is a mount top of Song Bai Ling, which is one of the largest tea producing region in Taiwan, if not the largest. Song Bai Ling is a mountain ridge in Nan Tou County (the same county for Dong Ding). It's a relatively low mountain tea in Taiwan, but still the mountain ridge elevation is about 500m, and tea plantation elevation is about 200-400m. From this mountain ridge, there is one of the 10 famous teas of Taiwan, Song Bai Chang Qing. But this tea seems to have vague definition, since tea bush varietals used and processing method are both similar to some other Taiwanese districts. I don't know if Bi Feng Tea (yours) is similar or same as Song Bai Chang Qing. So show us more pictures of the tea please!
Besides, according to the label, your tea is probably some award winning tea!
