Since ancient times, most of China's tribute tea, traditional famous teas, and contemporary newly created famous teas have originated from high mountains. Why do high mountains produce good tea? There are several reasons:

1. Natural Selection: Research indicates that the origin of tea trees is in the rainy and humid primitive forests of southwestern China. Through long-term historical evolution, they have gradually developed a preference for warm, humid, and shaded living conditions. The secret behind high mountains producing good tea lies in their superior ecological conditions, which precisely meet the growth requirements of tea plants.

2. Abundant Rainfall: Generally speaking, within altitudes of 2,000 meters, rainfall increases with elevation. Studies show that when tea plants have sufficient water, the condensation of sugar compounds formed through photosynthesis becomes difficult, and cellulose is less likely to form. This allows the raw tea leaves to remain fresh and tender for an extended period without becoming coarse or aged.

3. Fertile Soil: Soil is the natural foundation for tea tree growth. The nutrients and water required by tea trees are obtained from the soil, so the physical and chemical properties of the soil are closely related to tea tree growth. Lu Yu's "The Classic of Tea" from the Tang Dynasty states: "The best soil is rocky and fragmented, the medium is gravelly, and the poorest is yellow earth." Modern research also shows that the soil in high mountain tea gardens is well-weathered, contains more gravel, has good permeability, and is rich in organic matter and various mineral nutrients, including the major elements and trace elements needed by tea trees. As a result, tea trees grow robustly, and the effective quality components and various health-beneficial nutrients in the tea leaves are abundant.

4. High Mountains Are Often Cloudy and Misty: When sunlight hits clouds and mist, it is refracted by water droplets in the air, strengthening the red and yellow light waves—similar to what is observed in a rainbow. This enhances photosynthesis within the tea plants, directly increasing the amino acid content in the tea leaves.

5. Lush Vegetation in High Mountains: High mountains are rich in vegetation, which contributes to soil improvement. Fallen leaves and branches enrich the soil with organic matter, and extensive root systems promote good soil structure.
