There may be few substances in the world that are so closely related to human beings as water, but so far people's understanding of its essence is still extremely limited. Water is the basic and important substance in nature, and it is also the most studied but not fully understood substance.

Water is not only the main component of life, but also participates in the whole process of human metabolism. It is the only carrier of nutrient transportation and metabolic waste discharge.
