It seems a bit silly to ask this question, but the more people ask, the more people get lost. To understand this question, we have to re-educate everyone about what is mineral water and what is pure water, and let everyone judge.
Chinese have had a soft spot for mineral water since ancient times. Lu Yu wrote in the "Book of Tea": "On the mountain, in the river, under the well." Lu Yu also made a more detailed decomposition of the spring water. Tea people of all generations have unique opinions on spring water, and Emperor Qianlong believes that the light water is the best. He specially made a silver bucket, used to weigh the weight of the world's famous springs, after careful comparison, that Beijing Yuquan water is the lightest, so the imperial seal as the world's first spring, but also personally wrote the article "Yuquan Mountain the world's first spring record". It can be seen that the ancients had a deep understanding of spring water.
In modern times, urban water has been changed to tap water, and many children have never even seen real mineral water, coupled with various pollution, a lot of water can no longer be directly drunk. The mineral water we can buy in the supermarket is also a factory built by the manufacturer in a remote mountainous area, and the natural mineral water is filtered and then sent to the city for us to buy. However, the cost is relatively high, and it is impossible for most people to use it in their daily lives. However, the real natural mineral water is a good water that is pollution-free and retains most of the mineral elements, and as for the different water intake points, it is just a different style and mineral content.
Next, let's talk about what pure water is. Purified water is colorless and transparent water that has been processed in a specific way from a water source (usually tap water) that meets the hygienic standards for drinking water. Processing methods include distillation method, reverse osmosis method, ion exchanger method, electrodialyzer method, etc. The purified water produced is sealed in a container without any additives and ready to drink. However, due to the special production process, the mineral elements contained in it are no longer the ideal range required by the human body, and there are different opinions on whether it can be drunk for a long time.
I think, seeing this, most people will have their own judgment, as people who have been engaged in the tea industry for many years, we must think that mineral water is the best to make tea, and it is more suitable for long-term drinking. But why are there still many people who sell tea who say that it is better to make tea with pure water? There must be a demon when things go wrong, and making tea with pure water has certain characteristics, that is, the taste is smoother, even if it is a very poor tea, it can feel smooth and soft with pure water, so that consumers think that the tea is very good. Of course, attentive old tea lovers will find that pure water is not "active", there is no change and layering, and a lot of the fun of kung fu tea is lost. On the contrary, if you use very high-quality mineral water to make tea, the shortcomings of tea will be clearly exposed, and the difficulty of making tea will also increase, which is why some merchants who sell tea promote the use of pure water to make tea against common sense.
Society is progressing, and industrial products such as pure water have many uses in cities, but we cannot generalize and dismiss our traditional products for the sake of profit. Advances in technology have not yet reached the point where nature has completely replaced them, just as the best teas on the market are naturally occurring, not synthetic. If pure water is better, there will be no need for so many mining water manufacturers.
