Miyi refers to the mineral water produced in Miyi County, Panzhihua City, Sichuan Province, and its oxygen content refers to the dissolved oxygen content in the water. According to the data released by official website, the government of Miyi County, the oxygen content of Miyi mineral water is 7.2 mg/L. The higher the oxygen content, the better the metabolism and immunity of human body, which is good for the health.

In addition, besides Miyi mineral water, there are some other brands of mineral water with high oxygen content, such as Yun Rui oxygenated natural mineral water in Qinghai, with an oxygen content as high as 34.2 mg/L.
