In an era of quick monetization, the best brand stories often start with users.

When people on social platforms spontaneously unearthed the story of a "three-year promise" between CuiShengsheng and Sun Yingsha, a hidden foreshadowing was unexpectedly awakened. All the brand needed to do was follow the expectations of its audience and complete a mutual journey built on silent understanding.

Three years ago, Sun Yingsha, already a key player of the Chinese National Table Tennis Team, accidentally appeared alongside CuiShengsheng fries in a casual social media post.

This was not an arranged commercial shot, yet it was caught by attentive netizens. The brand responded naturally with lighthearted interaction.

Many netizens commented at the time that "dimensions have collided," even jokingly calling for an official collaboration.

Three years later, when the two officially announced Sun Yingsha as the global brand ambassador, this widely circulated story was rediscovered by fans and romantically labeled a "three-year promise."

Many even returned to the original post to check in, witnessing the beautiful arrival of this long-awaited moment.

The simple logic behind it is clear: as third-party observers sharply noted, the public trusts Sun Yingsha for her perseverance on the court. This trust seamlessly extends to the product because people see in her focus and dedication—beyond winning or losing—a reliable sincerity. That consistent honesty is itself the most powerful promise of quality.

Witnessed by millions of netizens, the story evolved from a "chance appearance" to an official partnership, completing a heartfelt, publicly shared emotional circle. This not only laid deep public support for the announcement but also infused the entire collaboration with warmth and sentiment.

Choosing a brand ambassador with matching values is like finding a soulmate. CuiShengsheng’s selection of Sun Yingsha was never a quick chase for traffic, but a deeply considered decision across audience, image, and brand value—creating a pure resonance of strength.

First, precise audience overlap and nationwide breakthrough. According to Weibo big data, Sun Yingsha, as a highly popular national sports figure, has influence far beyond the sports circle, covering teenagers to seniors and first-tier cities to emerging markets. This helps CuiShengsheng reach a nationwide audience, aligning with the brand’s market expansion goals. Her champion identity, carrying the spirit of "being the best," also echoes CuiShengsheng’s rapid rise to top sales volume after the announcement, strengthening the brand’s leading position in consumers’ minds.

Second, joyful resonance in personality and experience. This is the most delicate and widely discussed part of the partnership. Sun Yingsha’s pure, sunny personality aligns perfectly with the straightforward happiness CuiShengsheng delivers. The word "crisp" cleverly connects her genuine charm with the product’s distinct, crunchy texture.

From an industry perspective, this collaboration marked a critical image upgrade for CuiShengsheng. The perseverance, positivity, and health represented by world champion Sun Yingsha were smoothly translated into unique brand assets under the theme "Crispness is Strength."

Lastly, trust endorsement at the value level. The background of the national team means far stricter food standards than ordinary consumers. Sun Yingsha’s unintentional appearance three years ago, followed by her official endorsement today, sends a powerful quality signal. It silently tells consumers: this snack is approved by champion-level standards, trustworthy in health and quality. This gives the brand’s positioning of purity and health a tangible and credible foundation.

A Dual Harvest: Explosive Visibility and Mindset Penetration

A successful ambassador partnership is ultimately measured by both data and market performance. CuiShengsheng and Sun Yingsha’s "three-year promise" delivered results beyond expectations, achieving comprehensive success in brand visibility, consumer mindset, and commercial conversion.

Data shows the official announcement generated a total exposure of 420 million, brand overall voice surged by 689%, and the size of interested brand users increased more than 10 times. Numerous trending topics emerged, achieving a strong brand breakthrough through open public discussion.

The brand leveraged official channels, immersive zones, and direct links to seamlessly guide user interest to e-commerce platforms, shortening the conversion path.

Social media buzz quickly translated into tangible sales. According to online platform data, within 24 hours of the announcement, CuiShengsheng’s single-link sales exceeded 35 million RMB+, ranking No.1 on Taobao live streaming sales charts—proving the strong driving effect of social media momentum on the retail market.

A Mutual Journey Rooted in Purity

The partnership between CuiShengsheng and Sun Yingsha was a natural success: born from a lovely chance three years ago, forged by deep alignment in audience, image, and values, and rewarded with a triple harvest of visibility, mindset, and sales.

It is far more than a commercial collaboration between fries and a champion. It is a brand narrative about patience, faith, and sincerity. With its rapid rise to the top of the category after the announcement, it proves a simple truth: the most powerful marketing is telling real stories together with users; the most solid growth is moving forward side by side with consumers. Amid a noisy market, it clearly shows: pure product power touches hearts, and sincere long-termism always leads to success.
