Xuelian, a beautiful woman living deep in the mountains of the south, fell in love with Gangzi, a young hunter from a neighboring village. However, the local powerful bully Langya also covets Xuelian and wants to marry her as his concubine.
In order to achieve his goal, Lang Ya designed to kill Gang Zai and deceived Xue Lian that Gang Zai accidentally fell off a cliff and died while hunting. Xuelian was full of doubts. She didn't believe that Gangzi would leave her like this.
She came to the place where Gangzi died, crying day and night, heartbroken. She cried all her tears, and finally cried out blood. Her blood dripped under the tree, and the next year miraculously a tree filled with red heart-shaped beans grew there.
There is also a small black spot on these beans, which looks like Steel Boy's eyes. People have legends that this red bean was transformed from Snow Lotus's hard work and longing, so it is called "Acacia Bean".
The core of this tragedy is that pure love was strangled by Langya's conspiracy and power. And Xue Lian uses the most extreme image of life - hard work turning into beans to symbolize her undying love for Gang Zai, which is full of original tragic feeling!
