In modern tea, most of the tea is used to fill X, or excess nutrients are used to relieve greasyness.
However, in ancient times, the transportation, storage and preparation of food were single, and it was likely that only one type of food could be obtained for a long time. Whether it is to supplement vitamins or solve gastrointestinal problems, or to avoid "eating injuries", tea is the easiest to preserve and process the most convenient drink under the current conditions, and it is naturally a best-seller
In ancient China, three main goods were exported: tea, silk, and porcelain.
Tea, silk, porcelain were all stolen by foreigners in the late Ming and early Qing dynasties, and the Qing Dynasty had no fist products to the outside world, so it was very reasonable to close the country: I can't make money, why do I open my mouth, let those soil buns have a long insight?
ps: The foreigners stole the production process of porcelain, because the problem of raw materials never reached the level of Chinese porcelain, and then created "bone china", which is literally made of ashes mixed with clay.
In the ancient ** route, silk was afraid of moisture and light weight, and walked out of the Silk Road in the Western Regions.
Porcelain is heavy and does not need to worry about moisture, so it is mostly shipped to Europe from the South Seas.
Tea is both, and there is also an exclusive ancient tea horse road to Central Asia and South Asia, which is more convenient to ship due to the origin of the place, but it is easy to get damp and mildew. It is rumored that the Fujian profiteers in the Ming Dynasty did not pay attention to business ethics and sold the damp fermented tea on the road to the British, but the British felt great after drinking it, and they did not want to put the best green tea, so they went to the profiteers to buy moldy tea at a higher price, and then the profiteers saw the business opportunity and began to try to make fermented tea.
