Although Xia Siyu was wearing a swimsuit underneath, it wasn't one of those revealing types like the bikinis; it was a one-piece swimsuit. Over it, she wore a UV-protection robe-like thin fabric, which was actually a two-piece set to go with the swimsuit and didn't expose much. With a waist tie accentuating her slender waist, it's almost impossible to wear high heels while wading on the beach. Xia Siyu wore a pair of flip-flops, and it's her good body proportions that allowed her to dare such a bold move. Most female celebrities, even if they're tall enough, don't necessarily have such straight and slender legs as hers.
As for the man working with her, he was not a star from the entertainment industry, seemed to be some kind of model. Indeed, it was playing in the water—involving Xia Siyu splashing water on him one-sidedly, and running after each other by the sea, stepping on the waves.
