"Cailan Magazine" records: In ancient times, there was a woman who missed her sweetheart, but could never see her. She often cried under a wall, and her tears dripped into the soil. A plant grew up where the tears were shed. The flowers were charming and moving, and the color was like a woman's face. The grass had green leaves on the front and red on the back. It bloomed in autumn and was called "Broken Heart Grass". Ancient people often used flowers to express the sadness of separation between men and women. For those who have suffered setbacks in love, it is advisable to give them begonias, which symbolize bitter love and provide comfort.
