Chengdu is a city whose origin and destiny are intricately linked to water. Kuanzhai 321 natural spring water is drawn from a spring 321 meters beneath Longquan Mountain on the Chengdu Plain, from bedrock formed more than 100 million years ago. It is rich in the beneficial trace element strontium, which is so rare and precious that is called the “Giant Panda in Water”. The packaging is also unique and outstanding for its front and back-logo-imprinting technique and its giant panda pattern, reflecting both the precious rarity of strontium and the fact that Chengdu is home to the Giant Panda, China's national animal symbol.
