Kym Jinsha and Sun Chengxiao announce their marriage. With a 19-year age gap, how did their relationship evolve from widespread skepticism to public support?

On April 9, Chinese singer Kym Jin surprised fans by announcing her marriage to actor Sun Chengxiao, who is 19 years younger than her.

The couple shared photos from their marriage registration, appearing harmonious and affectionate, with little visible age gap—quickly sparking online discussion.

Their relationship, which became public in 2022, has now lasted four years. They reportedly met at a gathering, where Sun, then a graduate of the Shanghai Theatre Academy, pursued her by cooking over a hundred different dishes—an effort that ultimately won her heart.

Despite their sweet story, the relationship was not without controversy. In variety shows, some viewers felt Jin Sha’s gaze toward Sun carried a “maternal tone,” while Sun himself was once perceived as overly naive. Responding to criticism, Jin Sha remarked cleverly, “Maybe I’m not the fragile one—maybe I’m the fox.”

Speculation about their financial dynamics also circulated, but Sun later shifted public perception after appearing on the show Island Youth, where he demonstrated independence, practical skills, and a willingness to challenge inefficiency.

Over time, the narrative evolved—from skepticism to recognition of a mutually supportive partnership.

Sun proposed on December 24, 2025, and the couple has now officially tied the knot. They are also set to appear in The Romantic Journey of Wives 2026, though they emphasized that their marriage was not driven by the show.

Ultimately, marriage is more than emotion—it’s about compatibility in values, lifestyle, and shared direction. It seems this couple has carefully considered all of that.

Marriage is just the beginning.
Whether their age-gap relationship can defy expectations remains to be seen.
