The rapid transformation from an agricultural society to an industrial society

A single product is coffee beans of a single variety, origin, or roasting degree. Blending refers to coffee beans of different varieties, different origins or (and) different roasting degrees mixed together according to established concepts.

"When you first fall in love, you may be attracted to a certain trait of the opposite sex, whether beautiful or pure or willful, and you will plunge into the paradise of love. However, when they talk about love, they separate. They feel monotonous. They feel that others have shortcomings. They find the next one. As they grow older, they may find the next one. When they want to start a family, they consider it more comprehensively and pragmatically. If you want to live, you have to tolerate certain shortcomings of the other party. How can there be perfection in this world?" A single item is just like a couple, and a combination is just like a lover. However, you may also encounter a 'match' at the beginning, just like the first time you drink Espresso coffee, but you can't adapt and let her go. You think that she is not as pure and cute as the little girl. In fact, she is very suitable for your future life."

"Coffee is also like this, the single item is relatively lighter and less bitter. When you start drinking Colombia coffee, you will immediately be fascinated by its smooth and sweet taste; when drinking Ethiopian coffee, its unique strawberry, black berry, chocolate or orange flavor will make you linger. But as you drink, you want to try something else. At the end of the day, you want to combine several kinds to get a richer and thicker taste feast."

Not everyone is like this: drink too much of the single item and then drink the mix. "It's the same as falling in love. There are from the end, there are also from the single drink to the match, and then with the match 'divorce' and finally back to the single product. The world is full of people and things.
