Outside Hanshan Temple in Suzhou, the midnight bell tolls, reaching the traveler's boat. This poem depicts the elegance and tranquility of Suzhou, a land where a unique jade carving art, 'Suzhou Gong' (Suzhou Craftsmanship), flourished. It represents not only the pinnacle of skill but also the concentrated essence of Chinese jade culture, reaching its zenith during the Qianlong period of the Qing Dynasty, earning it the moniker 'Qianlong Gong' (Qianlong Craftsmanship).

The story begins in the Ming Dynasty. The prosperity of Suzhou jade carving was not an overnight success. As early as the Ming Dynasty, the jade carving master Lu Zigang was renowned for his 'Zigang Pai' (Zigang Plaques). He pioneered the art of shallow relief carving, integrating painting and calligraphy into jade, creating profound landscapes and figures within the small confines of a jade plaque. Lu Zigang's emergence established the delicate and elegant tone for Suzhou jade carving, laying the groundwork for the later 'Qianlong Gong'.

During the Qianlong period of the Qing Dynasty, with the nation at its peak, Emperor Qianlong developed a particular fondness for jade, sparing no expense to transport large quantities of high-quality jade from the Hotan region of Xinjiang. He was not only a collector of jade but also a promoter of jade culture. Under Qianlong's patronage, the Imperial Workshop established a jade workshop and recruited top jade carvers from across the country, especially from Suzhou. These Suzhou artisans, with their generations-old exquisite skills, ingeniously blended the graceful beauty of Jiangnan with the majestic grandeur of northern jade carving, forming the distinctive style of 'Qianlong Gong'.

The characteristics of 'Qianlong Gong' can be summarized as 'exquisite, detailed, ingenious, and elegant'.

Exquisite: Refers to the meticulous selection of materials. Jade artifacts from the Qianlong period often used top-grade Hetian jade, such as 'mutton fat' white jade and celadon jade, known for their warm, delicate texture and subtle luster. Before carving, artisans would cleverly conceive designs based on the jade's natural shape and color distribution, maximizing the preservation of its inherent beauty.

Detailed: Manifested in the complex carving processes and meticulous handling of details. A 'Qianlong Gong' jade piece often required dozens or even hundreds of steps, including design, cutting, grinding, and polishing. The carving lines are fluid, with every detail meticulously rendered. Whether it's the folds of a figure's clothing or the feathers and scales of birds and flowers, everything is carved with lifelike precision and utmost subtlety. For instance, the famous 'Jade Mountain Illustrating Yu the Great's Control of the Waters' from the Qianlong period, standing 2.24 meters tall and weighing 5 tons, features mountains, rivers, figures, and houses carved with incredible detail, a true marvel of craftsmanship.

Ingenious: Refers to clever conception and profound symbolism. Suzhou jade carvers excelled at using 'qiao se qiao diao' (skillful use of natural colors), cleverly incorporating the jade's natural hues into the design, adding layers and artistic appeal to the work. They were also adept at integrating auspicious patterns, historical allusions, and poetic imagery into jade carving, imbuing each piece with rich cultural connotations. For example, the common 'Fu Lu Shou' (Fortune, Prosperity, Longevity) theme combines images of bats, deer, and peaches to express wishes for a good life.

Elegant: Is the soul of 'Qianlong Gong'. It goes beyond mere technique, representing an aesthetic taste. The works are dignified and elegant in form, with smooth and soft lines. The overall style pursues subtlety and restraint, without ostentation. Whether it's antique-style vessels or scholarly ornaments, they all exude the aesthetic sensibility of literati, perfectly aligning with the refined ambiance of Suzhou gardens.

However, with the decline of the Qing Dynasty, 'Qianlong Gong' gradually faded into obscurity. But the flame of Suzhou jade carving never extinguished. After the founding of New China, Suzhou jade carving ushered in new development opportunities. Older generations of artisans generously passed down their traditional skills, while younger generations of jade carvers, building upon tradition, incorporated modern aesthetics and innovated. Today, Suzhou jade carving is a national intangible cultural heritage, with a large number of outstanding jade artists emerging. They uphold the essence of 'Qianlong Gong', constantly innovating in themes, techniques, and forms of expression, making Suzhou jade carving flourish anew.

When we admire a beautiful Suzhou jade carving today, we are not merely looking at a stone; we are savoring a piece of history, experiencing a culture, and touching the heart of a craftsman. It carries the millennia-old accumulation of Suzhou's cultural heritage and witnesses the continuous transmission of Chinese jade culture. This is the charm of 'Suzhou Gong', an artistic light that transcends time and continues to shine brightly.
