"Chengyao Gao" (literally "Waist-Strengthening Cake") is a traditional seasonal delicacy in the Jiangnan region, enjoyed during the "Dragon Head Raising" festival on the second day of the second lunar month. Its name stems from the agrarian culture's humble desire for a strong, sturdy back capable of enduring the rigors of farm labor. According to *Qing Jia Lu* (Records of Seasonal Customs in Suzhou), a text from the Qing Dynasty, people in ancient times would deep-fry leftover *Nian Gao* (New Year's rice cakes) from the previous year and consume them as "Chengyao Gao," symbolizing the bolstering of physical strength to tackle the spring plowing. This custom was particularly prevalent in places like Suzhou, where a folk rhyme once circulated: "Eat a piece of Chengyao Gao, and you won't need medicine for strained muscles all year long"—a verse embodying hopes for both good health and a bountiful harvest. Legend has it that the visual design of Chengyao Gao was inspired by dragon scales; the diamond-shaped cake body symbolizes the dragon's form, subtly conveying the auspicious significance of the "Dragon Head Raising" festival—namely, the warding off of evil spirits and the welcoming of good fortune.

Amidst the morning mist of Shiquan Street in Suzhou, Huo Yuming gently traces the contours of a dragon-shaped Chengyao Gao resting on his counter. Surrounded by the fragrant steam of rice, he seems to catch a glimpse of his ancestors—farmers with sturdy rice cakes tucked into their waistbands as they toiled during the spring plowing. Born from an agrarian civilization, this pastry once served as the "energy bar" of the Jiangnan water towns; farmers would slice and deep-fry their leftover, hardened rice cakes from the previous year, then bind them to their waists to stave off hunger and sustain themselves against the grueling demands of spring fieldwork. Old-time Suzhou locals would jokingly remark, "Eat Chengyao Gao, and your back becomes as hard as iron"—a sentiment that served as both a testament to physical endurance and a prayer for a bountiful harvest. On the "Dragon Head Raising" festival of 2026, the Huo brothers breathed new life into this "hardcore" tradition. Taking the dragon as their muse, they reimagined the traditional square rice cake into a dynamic, fluid form—an intricate tapestry of soft white dragon scales interwoven with reddish-brown and golden dragon motifs. The dragon's eyes are inlaid with black sesame seeds, its whiskers crafted from spun sugar threads, and every delicate fold and crease subtly echoes the exquisite texture of Suzhou silk. This represents not merely an aesthetic innovation, but a dialogue with folklore spanning a thousand years: the Dragon—the ultimate totem of Chinese civilization—awakens upon this Suzhou-style pastry, allowing the memories of agrarian life to blend seamlessly with the auspicious omens of spring. II. The "Cold Process" Revolution: Making Intangible Cultural Heritage "Live" in the Present

The predicament facing traditional *Chengyaogao* (Waist-Strengthening Cake) once caused deep concern among the older generation of artisans: its dense, sticky texture tended to harden when cooled, restricting its consumption to specific festive seasons. The solution devised by the Huo brothers lay in a revolutionary "cold process" innovation:

1. **Cooked First, Then Refined:** The steamed rice cake is allowed to air-dry to a temperature of 30°C–35°C; after natural dehydration, it is ground into a fine powder. This process breaks down the starch structure, thereby reducing the density of the cake body.

2. **Shaping at Room Temperature:** High-temperature steaming is abandoned in favor of low-temperature compression molding, a technique that preserves the authentic aroma and flavor of the rice.

3. **Incorporating "Eight Treasures":** Ingredients such as rose petal jam, crushed pine nuts, and diced lard are added to create a harmonious new texture—one that is "sweet yet not cloying, glutinous yet not sticky."

This innovative process extended the shelf life of *Chengyaogao* from three days to ten days, ensuring that the cake remains soft and tender even when consumed cold. On the day of *Longtaitou* (the "Dragon Raising Its Head" festival) in 2026, Jufoulou restaurant released a limited batch of 1,000 dragon-shaped *Chengyaogao*; the entire stock was snapped up the moment it hit the shelves. One gourmet connoisseur marveled: "Bite through the golden sugar glaze, and the fragrance of pine nuts and the delicate notes of rose unfold in layers—it feels as though you are swallowing a mouthful of spring in Jiangnan."

III. The "Double-Sided Embroidery" of Heritage Preservation: The Art of Balancing Tradition and Innovation

As the fourth-generation inheritors of the intangible cultural heritage of Suzhou-style pastries, the Huo brothers embody a philosophy of craftsmanship best described as: "Upholding tradition without being rigid; innovating without losing one's roots."

• **Upholding Tradition:** They strictly adhere to the ancient "three steamings, three kneadings" method, maintaining a precise rice flour ratio of 7:3 (glutinous rice to non-glutinous rice) to ensure the cake body possesses the perfect balance of softness and resilience.

• **Innovation:** They have introduced modern food engineering principles to develop their "cold processing" technology, thereby solving the long-standing challenges associated with the industrial-scale production of traditional pastries.

• **Cross-Disciplinary Collaboration:** They partnered with an art academy to design custom molds featuring dragon motifs, incorporating elements from the renowned painting *Prosperous Suzhou* into the bas-reliefs on the cake's surface—transforming this piece of intangible cultural heritage into a tangible work of art. This balance is perfectly exemplified at the Suzhou Noodle and Pastry Heritage Center on Shiquan Street: gourmets marvel not only at the visual appeal—or "aesthetic value"—of the dragon-shaped pastries but also applaud the traditional recipe featuring a filling of rose-infused lard. Huo Yugen, a recognized inheritor of Intangible Cultural Heritage, quips with a smile: "The craftsmanship of our ancestors shouldn't be locked away in a glass cabinet; it must be made to feel 'trendy' to young people—only then can it be considered true heritage."

IV. Contemporary Interpretations of Folk Symbols: Collective Memory in a Single Bite

The surging popularity of the "Dragon-Shaped Waist-Strengthening Pastry" (Chengyao Gao) reflects the Suzhou people's deep-seated devotion to a sense of "ritual":

• **Reviving Memories of Spring Plowing:** Young parents bring their children to craft these dragon-shaped pastries, sharing the tale of the "farmer's waist-pastry"—a tradition that allows agrarian civilization to be reborn through parent-child interaction.

• **Urban Festival IP:** Shops along Shantang Street and Pingjiang Road have curated "Spring Gift Boxes"—combining the dragon pastries with peach-blossom stationery and Suzhou embroidery bookmarks—creating a quintessential "Impression of Suzhou" that has become a must-buy souvenir for tourists.

• **A Metaphor for Wellness Philosophy:** Modern people have ascribed a new meaning to the concept of "waist-strengthening": office workers with sedentary lifestyles view the pastry as a waist-friendly snack, while practitioners of Traditional Chinese Medicine (TCM) extol the warming properties of its glutinous rice, which is believed to nourish the spleen and stomach.

At the bustling Guixiang Dafang Pastry Shop on Guanqian Street, a white-collar professional remarked with a touch of nostalgia: "I used to think of *Chengyao Gao* as 'old people's food,' but now—thanks to the dragon-shaped design—I’m more than willing to pay for the cultural experience it represents."

V. The Future of Intangible Cultural Heritage: From the Hearth to the Stars

The vision shared by the Huo brothers is to transform Suzhou-style pastries into "edible cultural landmarks":

• **Tech Empowerment:** Developing freeze-dried versions of the dragon-shaped pastries—which retain 90% of their original texture and flavor upon rehydration—thereby paving the way for this intangible cultural heritage to enter the realm of space food research and development.

• **Digital Heritage:** Utilizing Augmented Reality (AR) technology to recreate the scene of frying pastries—vividly described in the classical text *Qing Jia Lu* as "tender yellow emerging from shimmering oil"—allowing history to come alive at one's very fingertips.

• **Global Narrative:** Showcasing the dragon-shaped pastry at the Venice Biennale as a medium to interpret the fascinating interplay between "Eastern agrarian wisdom and modern minimalist aesthetics." Much like the golden dragon leaping vividly from the surface of a pastry, Suzhou’s intangible cultural heritage is breaking free from the confines of locality, soaring with a newfound lightness. Yet, the true guardians of this “living heritage” remain—as always—the warm, pliable glutinous rice flour in the hands of the artisans, and the timeless ethos—unchanged for a thousand years—of “eating only what is in season.”
