Introduction to Fengqing Tea Garden: Kou Zhun, the Prime Minister of the Northern Song Dynasty, was demoted to Guilin. Kou Zhun discovered that the tea from Nanxi Mountain was brewed by the water of Bailong Spring at the foot of Nanxi Mountain, and it had an unusual fragrance. So he sent tea leaves and Bailong Spring water from the foot of Nanxi Mountain as tribute to Emperor Taizong of Song Dynasty. Emperor Taizong of Song Dynasty was so happy after drinking the tea that he immediately reinstated Kou Zhunguan to his post and built the imperial tea garden - Nanxi Tea Garden at the foot of Nanxi Mountain. From then on, the new tea picked every year was paid tribute through Nanxi Tea Garden, and later generations slowly began to drink and taste tea at the foot of Nanxi Mountain.
