In the private room of Jin Sinan, located in Longyan, Fujian, Huang Wei shared a deep insight: “The finest of Jin Sinan is Xiaoye Nannan, Ye Ruzhi, Qiruo Lanlan, Qingxiangwuxie, and Yunguichuan. Among these, Sichuan's variety is considered the top grade.†The room was filled with wealthy merchants, collectors, and enthusiasts who were all captivated by the allure of this rare wood.
Beyond the collections of northern monks, Huang Xi emerged as a key figure in southern Jin Sinan collecting. Over the past decade, he invested heavily, amassing a vast collection of Phoebe wood. His private hall, while impressive, was just the tip of the iceberg. He also maintained two large warehouses—one in the suburbs of Longyan and another in Dongyang, Zhejiang—where his most valuable pieces were stored.
Huang Hao, a close friend, remarked, “Jin Sinan carries the fiery passion of the southern people, but it also brings uncertainty, embarrassment, and amazement.†Born in Shuxiangzhijia, Huang Hao grew up in Shanghai, where he became familiar with the lifestyle of the city’s elite. Later, he returned to Fujian for business, but a few years ago, he made a sudden shift from real estate to the world of antiquities.
His journey began with jade and calligraphy, but a chance encounter with Jin Sinan opened a new door. This experience led him to step away from his business and embrace a more refined, contented life. As he put it, “Since ancient times, scholars have spoken of 'nourishment.' I lived my life searching for it, and now I find it in wood.â€
Inside his Jin Sinan Private Hall, two small tea rooms stood alongside a modest museum dedicated to the art of Phoebe. Displayed were various pieces of Jin Sinan furniture—stools, cabinets, and chests—all left unpainted to showcase their natural luster. Their glossy texture alone was enough to make them masterpieces.
However, Huang Xi admitted that his journey was not without missteps. At the height of the "fever," he would buy anything he came across, often spending exorbitant sums. Some pieces turned out dull and unsatisfactory, leading to losses. But through reflection and guidance from local experts, he eventually found his way.
He traveled extensively, visiting famous mountains, renowned collections, and even exploring areas like Bijie in Guizhou and Yunnan, where newly excavated Nanmu was being uncovered. In Sichuan and Ganzhou, ancient logs buried for centuries were unearthed, some revealing golden textures that rivaled silk in beauty.
One day, a farmer near Chengdu called him excitedly, claiming to have discovered a massive Nanko log used for tea trays. The wood was covered in golden waves, resembling flowing silk. Huang Xi immediately rushed to see it, and after a swift negotiation, he paid two million yuan for the best portion of the piece.
Today, four sections of this golden silk Phoebe are displayed in his hall. Like a porcelain expert identifying blue-and-white ceramics, these pieces serve as "specimens of Jin Sinan" for collectors from north to south. Each section displays full-screen gold filaments, glowing like flames, shifting in color and pattern.
As Jin Sinan’s price soared, it quickly attracted speculative investors. Local hot money drove prices sky-high, with some pieces selling for millions in a single day. Many now treat Jin Sinan like a form of "gambling wood," similar to the popular "gaming jade." Buyers purchase logs at certain prices, then have them cut open. If the inside reveals rich golden patterns, they can become instantly wealthy. If not, they lose everything.
Huang Wei explained, “From the outside, Jin Sinan often looks unremarkable, indistinguishable from ordinary Phoebe. That’s what makes it so unpredictable—and perfect for gambling.†He added, “But betting on wood is really taking a risk.â€
He described how a seemingly ordinary tree could reveal a dazzling world of golden light when cut open. “The water-like waves, tiger-like patterns, and coin-like textures are mesmerizing,†he said, reflecting on his decade-long experience.
According to Huang Xi, there are many varieties of Jin Sinan on the market, but only those meeting specific criteria—like high gold filament coverage—are truly authentic. Its legendary nature lies in its ever-changing internal patterns, which evoke a sense of depth and mystery. The wood also has a subtle fragrance that lingers for centuries, embodying quiet elegance—a trait that resonates deeply with Chinese literati.
Historically, many scholars favored Phoebe for its hidden brilliance. This quality mirrors the essence of Chinese culture—unassuming on the outside, yet rich and radiant within. Jin Sinan woodcarving has become highly sought after, with pieces like the Jinsi Phoebe Buddhist temple in Beijing’s Lama Temple and the tens-of-meters-long Wubai Lohan sculpture in Wuxi’s Great Buddha Museum being regarded as treasures.
Today, the value of Jin Sinan continues to rise, and its pricing methods have become increasingly bizarre. At the Gongfu Museum in Wangfujing, a pair of top-tier Jin Sinan cabinets fetched over 3 million yuan, while a screen sold for over 1 million. Even a simple Arhat bed could reach 700,000, far exceeding the value of similar red rosewood items.
Initially, Huang Xi felt this trend was unreasonable, marking an era of turmoil in the collection scene. The once-pure aesthetic of literati culture had been overshadowed by capital-driven speculation. Now, acquiring a single piece of Phoebe could cost over a million yuan.
Despite this, Huang Bo pointed out another unique characteristic of Phoebe: its “resurrection†ability. Even if buried in mud or river water, the wood can absorb minerals, mineralize, and develop a new visual and aromatic quality. This natural transformation gives it a magical, almost mystical appeal.
Now, with prices soaring and speculators flooding the market, concerns about sustainability have grown. Areas rich in Jin Sinan, such as Yun Guichuan, have been heavily exploited, with young collectors buying up available resources. Fortunately, the Sichuan government has imposed restrictions on the export of large Nanmu, preventing further depletion.
For Huang Huai, the greatest worry remains the excessive luxury and greed that could lead to the extinction of Phoebe. Yet, despite the challenges, the allure of Jin Sinan continues to captivate, preserving its legacy as both a material and a symbol of cultural richness.
