How a Top Mathematician Sparked Cartier's Latest Viral Moment

The Fields Medal—often called the Nobel Prize of mathematics—was announced yesterday. Chinese mathematician Wang Hong has become one of the first Chinese nationals to win the prize, and only the third female winner in its history.

When Wang accepted the medal at the ceremony on July 23, the seemingly academic event created an unexpected fashion moment on Chinese social media. Users quickly noticed she was wearing a Clash de Cartier necklace and ring—pieces she frequently wears to academic events and other public appearances.

While the general public might not grasp her complex math research, they were quickly drawn to Wang's "intellectual chic.” This sudden interest sparked a desire to buy the Clash de Cartier jewelery.

Related posts on Xiaohongshu have already drawn thousands of engagements. Users commented that Wang's choice of jewelry elevates Cartier's brand image, creating a much better marketing effect than a standard celebrity endorsement. Many even suggested that Cartier should make her an official brand ambassador.

This year, "The Dream of 900 Million Girls" became a trending topic on Chinese social media. These "dreams" feature women like Nobel Prize winner Tu Youyou, scientist Yan Ning, Huawei CFO Meng Wanzhou, astronaut Wang Yaping, and Olympic champion Eileen Gu. The trend highlights that young Chinese women today dream of reaching the top of their careers, rather than simply finding romance. Wang Hong naturally fits right into this new lineup of role models.

Female shoppers are getting tired of traditional celebrity marketing, especially when it relies on internet influencers or viral stars. Instead, figures known for their brains and expertise are proving much more persuasive. 

Consumers no longer just want a product because a famous face is wearing it, and they don't buy the idea that a single lipstick will change their lives. They want their purchases to reflect the independence, focus, and intelligence that these top-tier professionals represent.

Luxury and premium brands have clearly caught on to this shift, bringing in more accomplished, smart women to represent their products.

In May, well-known Chinese host Chen Luyu attended the Cannes Film Festival, where her elegant red-carpet outfit—a crisp white shirt paired with black wide-leg pants—won wide praise. She wore Cartier jewelry with the look, and was seen wearing a TAG Heuer watch in her other Cannes outfits. Recently, she has also become a regular guest at major events for luxury brands like Hermès and Rolex.

Even though she is already a household name in Chinese media, Luyu has enjoyed a career revival through her podcasts and various variety show appearances. Her strong professional skills, sincere interview style, and image as an independent woman have made her a role model for a younger generation.

Similarly, Zhou Yijun, another respected Chinese journalist, has been working closely with fashion and beauty brands. She hosts a podcast for the premium Chinese fashion brand Songmont and recently attended a product launch for Lancôme.

For luxury houses, these highly accomplished professionals reflect the true meaning of luxury much better than mass-produced internet influencers. They offer something money can't easily buy: true exclusivity.

With "influencer fatigue" on the rise, luxury brands urgently need to add more cultural depth to their image. While traditional celebrities still drive huge sales, partnering with smart, professional role models might be exactly what the industry needs right now.
