Why is the soda in Xuzhou tap water so big? Is drinking too much harmful to human body?

I feel that people in Xuzhou basically drink pure water. My family drinks Runfa 1 barrel and 7 yuan 1 barrel, but it is best not to drink pure water at ordinary times. The mineral content of tap water in Xuzhou is still relatively high (it seems to be). Drinking boiled water at ordinary times is good for your health. If you drink tap water alone, it should have little effect on your health. After all, most of the old people in Xuzhou drink boiled water. There is no harm ~ if you want to reduce water and alkali, there are many indigenous methods, such as putting the cut pulp in a kettle. In fact, the most direct way is to pour hot water directly without drinking it first, and let it precipitate automatically when it is cold. In fact, there is no need to worry about these things, and the impact on the body is actually not great. Sometimes caring too much about your health is harmful to your health. Now science is not absolutely correct.
