It is a nationally classified confidential fungus species, most notable for its prominent health benefits in weight loss, beauty, anti-cancer, and anti-radiation.

"Water" refers to the Zijiang River water. The water quality in the Anhua section of the Zijiang River is the cleanest and most environmentally friendly, pure enough to drink directly. Especially the streams flowing into the Zijiang, descending directly from mountains over 1600 meters high, where the landscape creates the excellent quality of Anhua Dark Tea.
"Fire" refers to the most traditional and crucial processing step in Anhua Dark Tea—drying over pine wood open fire. This process forms the unique color, aroma, and flavor of Anhua Dark Tea: color—dark brown and glossy, aroma—pine scent, taste—pine flavor. It also helps reduce the caffeine content in Anhua Dark Tea, contributing to health benefits such as calming the nerves, improving sleep quality, and harmonizing the stomach.

This layer is described as: "The best tea grows on weathered rock, medium-grade on gravelly soil, and the lowest grade on yellow earth. The soil is fully weathered, contains many gravels, is variegated, has good permeability, and is rich in organic matter and various mineral nutrients." The tea leaves grown here are rich in effective quality components and healthful nutrients, such as potassium, nitrogen, selenium, calcium, sodium, fluorine, etc.
