The editor introduces the growth habits of coffee.

Coffee trees like mild temperatures during the day and less than two hours of direct sunshine, so if there is a lack of afternoon showers or fog to report every day, local farmers have to plant many taller trees in the coffee garden for shade. At night, they want an environment of about ten degrees Celsius but not too low, because too warm will make the coffee berries grow too fast to produce small, strong, hard and high-quality coffee beans; in case it is too cold to frost, the coffee trees will freeze to death.

Based on these characteristics, the promised land suitable for Arabica coffee is mostly located in countries with alpine terrain between the Tropic of Cancer, which is also known as the coffee belt (Coffee Zone/Coffee belt).

As an elegant, fashionable and high-grade drink, coffee has long been popular all over the world, and it has been listed as the first of the three major beverages (coffee, tea and cocoa) in the world. Coffee is also grown in 76 countries and regions all over the world. In 1983-1984 alone, the world's coffee output reached 5.5 million tons, and the export volume was 4.2 million tons. Among them, Brazil in South America, known as the "coffee kingdom", has the largest production and export volume. In spite of this, the hometown of coffee is not in Brazil, but in Ethiopia in Africa. to this day, there is still a large area of wild coffee forest in the dense jungle of the southwestern province of Cafa. The word "coffee" comes from the place name "Kafa".
