In 1893, the American explorer W.W. Rockhill described Gyegu as the only town in northeastern Kham where Chinese merchants were allowed to reside. Roads radiated in every direction -- to Chamdo in ten days, to the capital of Derge in six, to Lhasa in nine via the northern route. The better grades of tea traveled the Janglam, the northern branch of the China-to-Lhasa trade route, passing through Kangding, Dawu, and Kardse before reaching Gyegu. When trade peaked in the early twentieth century, the permanent population was modest -- about 100 Tibetan families and 300 to 400 monks at Dondrub Ling monastery. But the town's population doubled whenever Han and Hui merchants arrived from Sichuan and the Tibet Autonomous Region, joined by Mongol traders from Shaanxi and Gansu. The wealth generated by this commerce made Gyegu home to some of the richest families on the entire Tibetan highland.

Unlike much of central Tibet, Gyegu and the wider Yushu prefecture were never firmly under the Gelugpa order's control. The area fell within the Nangchen kingdom, governed by local chieftains called Drawupon, and this different balance of power allowed older Tibetan Buddhist schools to flourish. The Karma Kagyu lamaseries of Domkar Gompa and Thrangu Gompa, the famous Mahavairocana Temple -- popularly called Wencheng Temple for its association with the Tang-dynasty princess -- and the religious site of Gyanamani with its billions of mani stones all cluster near the town. Before collectivization in 1958, over 25,000 Buddhist monks and nuns lived in the Yushu prefecture, with roughly 300 incarnate lamas among them. In Nangchen county, monks and nuns constituted between 12 and 20 percent of the population. Gyegu also holds a somber distinction: the 9th Panchen Lama died here on December 1, 1937, en route back to Tibet after the 13th Dalai Lama's death.

The wealth that caravans brought to Gyegu expressed itself most visibly during two annual celebrations: the Tibetan New Year Festival and the Gyegu Horse Festival. Khampa culture prizes horsemanship, and the festival drew riders and traders from across the plateau, turning the town into a spectacle of mounted skill, fine dress, and competitive display. Goods for trade and barter arrived from every direction, and the festival served as both market and social event -- a place where the business of the steppe and the pageantry of Khampa identity merged. The tradition persists today, a living connection to the era when Gyegu's significance was measured not in administrative boundaries but in the volume of goods and people passing through its valley junction.

Getting to Gyegu once required a two-day drive from Xining along China National Highway 214, crossing the Bayankara Mountains and fording the upper Yangtze 25 km before arrival. That changed in 2009, when Yushu Batang Airport opened 18 km south of town at 3,890 meters -- the highest airport in Qinghai Province. The modern town has grown from the old Tibetan trade mart into a cluster of four subdistricts that together form the urban core of Yushu City. The name Gyegu still clings to the place in common usage, preferred over the administrative designation by locals and travelers alike. At 3,700 meters, the thin air slows everything down -- steps feel heavier, decisions take longer, and the light has a crystalline intensity that makes the surrounding mountains appear closer than they are. The valley junction where two rivers meet remains the same geographic fact it has been for millennia.
