In the vast world of tea, dark tea stands out with its unique charm. Anhua dark tea, in particular, is a shining gem within the dark tea category, and at the heart of what makes this tea exceptional is the mysterious and unique Glacial Conglomerate. A specific land produces a distinctive tea. The unshakable status of Anhua dark tea in the tea world owes much to the environment shaped by Glacial Conglomerate.

Drinking tea is a common practice for adults. However, in daily life, we rarely see children drinking tea. Many parents allow their children to drink regular soft drinks and carbonated beverages but seldom permit them to drink tea. Zhu Haiyan, Director of the Horticultural Culture Research and Dissemination Center at the College of Horticulture and Landscape Architecture at Hunan Agricultural University, explains that there are two main reasons why we seldom see children drinking tea in everyday life. Firstly, children do not like the bitter taste of tea. More importantly, people believe that tea has a certain stimulating effect which may be detrimental to children's growth and development, potentially harming their spleen and stomach. In fact, these views are one-sided. "Scientifically speaking, drinking safe and hygienic tea, without consuming it too strong, can bring many benefits to children," Zhu Haiyan says. Firstly, moderate tea consumption helps to reduce fat and promote weight loss. According to relevant surveys, more than one-fifth of school-aged children in major cities in China suffer from varying degrees of nutritional excess, leading to numerous cases of obese children and those with high blood pressure and high cholesterol levels, severely affecting their physical and mental development.
