唐代詩人王維曾寫到：紅豆生南國，春來發幾枝？愿君多采擷，此物最相思！紅豆自古以來就被賦予濃厚的相思之意。那么，紅豆為什么會叫"相思豆"呢？快來看看下面的解釋吧！ 

    It is said that long ago there was a man who went off to war. His wife was leaning against a big tree in a high mountain while hoping for her man to return home day and night. Because of her continual longing, she was sobbing under the big tree all the time. After her tears dried, she dropped blood from her eyes without noticing. To everyone's surprise, when the dropped blood fell to the ground, they became red beans. The red beans rooted and then grew into big trees. Soon after, red beans filled the branches and people named them love beans. Day after day, spring to autumn, the fruits slowly changed into the most beautiful seeds：Love beans. 

    Red beans have a very profound cultural foundation. A red, love bean is very big, with a diameter of about 9 millimeters. This kind of bean has distinct characteristics. They are very hard and hearts shaped, and have a similar color to blood. They can be stored for a very long time without rotting, or fading in color. More so, its shape and all the other lines are heart shaped. 

    In folklore, red beans are considered intelligent and lucky. If a boyfriend gives red beans to their girlfriends as presents, it means that they want to make a commitment. When a bride wears red beans on her wrist or neck, it means that she will lead a happy life. If married couples put six red beans that have been sworn upon under each pillow, it is said that the couple will maintain their eternal love. 

    Currently, red bean jewelry is sweeping southward. Fashionable women are proud of wearing red bean jewelry. Male and female lovers rush to choose jewelry for each other to show their love.

    Red Beans have always stood for hope from as far back as the ancient periods.
