"It is good for water, and water for people." Water is the foundation of all things, the source of life, and an indispensable material for human beings. In the pursuit of quality of life today, in front of a dazzling array of shelves, people stop for a bottle of clear "Wu Dalian Pool Mineral Water". This natural gas-rich, long-lasting product comes from the Wudalianchi Nature Reserve in Heilongjiang Province, one of the world's three major cold springs. It is a deep water containing carbonic acid gas that has undergone hundreds of thousands of long periods of dissolution and mineralization. The volcanic fissure overflows the surface and is the best mineral spring confirmed by the practice of many health groups in the north for thousands of years.
