A brief description of the environment where Jiannanchun comes from:

Jiannanchun is located in the world civilization zone near 30 degrees north latitude. It is connected to the Longmen Mountains to the north and the Chengdu Plain to the south. It is the transition zone from the Qinghai-Tibet Plateau to the Sichuan Basin. , has a typical subtropical monsoon climate, with warm and humid climate, numerous and active microorganisms, resulting in Jiannanchun's unique rich, full and mellow style. The yellow clay in Sichuan is acidic soil and contains a variety of trace components. The pit mud made of yellow clay is a hotbed for cultivating microorganisms.

During the Quaternary Pleistocene epoch two to three million years ago, Mianzhu Longmenshan National Geopark was covered by glaciers and was holy and flawless. More than a million years later, the remains of the glaciers were buried deep beneath the earth's surface, forming a mineral-rich glacial accumulation layer that is isolated from modern society. The clean ice and snow melt water from Jiuding Mountain penetrates layer by layer and reaches the ancient Ice Age strata. After more than ten years of natural leaching and percolation, it converges into a treasure-like water vein, hidden deep in the land of Mianzhu.
