Talking about the ancient saying - the ancient Chinese tea-horse culture
China, in ancient times...
China will take tea to trade with the surrounding nomads in exchange for their horses, called tea-horse culture....

If they want to get enough alkaline food, it is not enough to drink milk/sheep milk because milk/sheep.
Although milk is an alkaline food, it can't be drunk too much at one time, so they traded vegetables/fruits/wine/tea with China.
Among them, the trade of tea is the largest, so it is called "tea horse culture".
