When Tang Dynasty poet杜牧 (Du Mu) wrote the now-famous line “A single rider in red dust brings a smile from the beloved—none know it’s just lychees arriving,” he immortalized not only the beauty of Yang Guifei, but also a fruit. Few poetic lines capture such rich layers of history, romance, politics, and logistics.

But behind the delicate flavor of a lychee was a vast imperial system mobilized to satisfy a royal craving. In an era without refrigeration, highways, or airplanes, how did lychees—highly perishable subtropical fruits—arrive fresh and fragrant at the palace of one of the most famous women in Chinese history?

Let’s peel back the layers of this intriguing tale.

A Fruit Fit for a Consort

Yang Guifei, or Yang Yuhuan, was the favored consort of Emperor Xuanzong of Tang. Renowned for her beauty and charm, her tastes helped shape court culture—and her fondness for lychees became legend. But unlike today, when lychees are a supermarket staple in summer, obtaining fresh lychees in 8th-century Chang’an (modern-day Xi’an) was a monumental challenge.

Lychees grow in warm, humid climates. During the Tang Dynasty, two regions were known for their lychee production: Bashu (modern-day Sichuan and Chongqing) and Lingnan (Guangdong, Guangxi, and Hainan). Bashu, although cooler today, had a warmer climate in Tang times, suitable for lychee cultivation, particularly in areas like Hejiang (合江) and Fuling (涪陵). Lingnan, with its ample sunshine and long growing season, produced the sweetest lychees.

The challenge? Chang’an is over 2,000 kilometers from Lingnan, and at least 1,200–1,500 kilometers from Bashu. And lychees spoil within days of harvest.

The “Lychee Expressway”: Engineering for Love

How does an emperor ensure his beloved enjoys fresh lychees from the far reaches of the empire? With infrastructure.

The answer lay in the Ziwudao (子午道)—an ancient road first developed during the Qin Dynasty to connect Chang’an to the south. By the Tang era, this route had been expanded and reinforced. Emperor Xuanzong ordered enhancements to this road specifically to facilitate faster lychee transport, giving rise to the name “Lychee Road” (荔枝道).

Relay stations, or yizhan (驿站), were established along the route. These were strategically spaced outposts where messengers could rest or swap horses. In the case of lychee transport, they functioned like pit stops for what we might call an ancient cold chain.

What was the speed of this operation? We can estimate based on wartime courier speeds. When the rebel general An Lushan launched his revolt from Fanyang (modern Beijing), the news reached Chang’an—about 1,500 km away—in just six days. That’s about 250 km per day on horseback. A similar pace would have allowed fresh lychees to reach Chang’an in 5 to 10 days, depending on the origin.

Still, the journey was perilous—for both horses and humans. Fast riding over rugged terrain could mean broken fruits and exhausted couriers. Yet, Yang Guifei’s lychees reportedly arrived whole and flavorful.

Ancient Cold Chain Logistics: Keeping Lychees Fresh

How did they manage this without modern refrigeration? The Tang couriers employed ingenious methods to preserve freshness.

Two primary techniques have been recorded:

  1. Bamboo Tube Preservation:
    Fresh lychees, still attached to their branches and leaves, were sealed inside bamboo tubes with a layer of mud. This natural packaging protected the fruit from pressure damage and slowed spoilage through insulation and humidity control.
  2. Wooden Box with Ice Pack Method:
    A more sophisticated version involved placing lychees and ice blocks inside a specially constructed wooden box with insulating layers of cotton and wool. This technique maintained a cool internal environment, keeping the fruit fresh for days—an early example of cold chain transport, a concept modern logistics relies on for perishable goods.

The use of ice, likely harvested and stored in ice cellars from winter, shows how advanced Tang logistical planning could be. These “cold boxes” were carefully sealed and transported by horse relays with maximum urgency.

The Southern Route: Lychees from Lingnan

Though Bashu was closer, Yang Guifei also enjoyed lychees from the farther Lingnan region, prized for their exceptional sweetness. The journey from modern Guangdong to Chang’an was more than 2,000 kilometers—a logistical nightmare by ancient standards.

Here, the Tang Dynasty appears to have taken a different approach: transplanting the entire lychee tree.

In what may be one of the earliest recorded instances of plant relocation for timed harvest, southern officials would uproot nearly mature lychee trees with soil and roots intact, placing them in large pots or crates. These were transported north by river or sea, then overland. By the time the tree reached Chang’an, the fruits would be ripening. The final harvest could then be rushed by horse courier to the palace.

One key official involved was Zhang Jiuzhang, military governor of Lingnan and younger brother to the famous poet Zhang Jiuling (who penned “The moon rises over the sea, and we share its light from afar”). His strategic gift of lychees earned him favor at court and eventual promotion to Minister of Revenue (户部侍郎). It was good politics—and smart branding.

Lychees and Scapegoats: The Burden of a Favorite

In later generations, Yang Guifei was scapegoated for the decline of the Tang Dynasty. Du Mu’s poem, romantic though it was, hints at a criticism: the imperial court’s extravagance—symbolized by galloping horses delivering exotic fruit—while the empire teetered on instability.

But the history of imperial lychee obsession predates Yang Guifei by centuries.

During the Han Dynasty, southern vassal kings sent lychees as tribute. The mighty Emperor Wu of Han even attempted to grow lychee trees in Chang’an’s Shanglin Garden, only to have them perish due to the colder climate. The failure was taken so seriously that the gardener was reportedly executed.

Later dynasties continued the trend. Even during the Qing Dynasty, lychees from Fujian were transported to the Forbidden City for the Emperor. For male monarchs, these indulgences were seen as symbols of power and authority. Yet, when Yang Guifei enjoyed the same treatment, she was framed as a femme fatale.

The double standard is hard to ignore. As history shows again and again, powerful women are often blamed for the ambitions and follies of the men who adored them.

Sweetness, Sacrifice, and the Silk of History

The story of lychees and Yang Guifei is not just about fruit—it’s about empire, engineering, and the emotional weight of imperial favor. It’s a tale of couriers galloping through valleys, of wooden boxes filled with ice, of botany and poetry and heartbreak.

Above all, it’s a reminder that even in an age of emperors, what moved mountains was sometimes just love—and a lychee.
