Modelled in the form of the laughing twins turned inwards to face one another, both standing on a large lotus leaf, atop a base of rolling waves one twin stands wearing loose robes open at the chest to reveal a ruyi-form necklace, his hair in two top-knots, in his right hand holding a large plantain leaf over his his shoulder, embracing his companion, similarly dressed with a loose robe to reveal a smaller ruyi-form necklace, with long hair trailing down his back and a bald patch on the top of his head, both hands holding onto a slightly opened basket to reveal the head of a tortoise.
Note: The Hehe Erxian, or the Two Immortals of Harmony and Unity, were believed to preside over happy marriages, and are adaptations of two famous poet-monks of the Tang dynasty, Hanshan and Shide. During the Ming and Qing dynasties, the twins were usually depicted holding a box, he, and a lotus stem. The homophone he provides a rebus for harmony.
