The Xumi Fushou Temple was designed in 1780 for a very specific guest. The 6th Panchen Lama, Lobsang Palden Yeshe, traveled all the way from Tibet to Chengde to congratulate Emperor Qianlong on his 70th birthday. This was not a casual trip -- the journey from Lhasa to the hills of Hebei Province covered thousands of kilometers across some of the most difficult terrain in Asia. To honor the visit, Qianlong commissioned a temple that would make the Panchen Lama feel at home, blending Chinese and Tibetan architectural traditions into a complex covering nearly 38,000 square meters. The result is a temple that looks unlike anything else in northern China, its red terraces and golden-roofed halls rising from a hillside slope east of the neighboring Putuo Zongcheng Temple.

The temple's architecture reads as a conversation between cultures. The main building, the Great Red Terrace, rises three stories on a three-story foundation -- six levels of ascending grandeur. At its center sits the Miaogaozhuangyan Hall, where the Panchen Lama preached during his stay. Nearby, the Jixiangfaxi Hall served as his personal residence, its roof sheathed in gold-plated copper tiles that still catch the afternoon sun. A seven-story octagonal pagoda, the Liuli-Wanshou -- the Glazed Tile Pagoda of Longevity -- anchors another corner of the complex, alongside a glazed tile paifang gateway. In the stele pavilion, a memorial plaque bears inscriptions in four scripts: Manchu, Chinese, Mongolian, and Tibetan. Those four languages inscribed on a single stone capture the ambition of the Qing dynasty at its zenith -- an empire that governed peoples speaking dozens of languages and worshipping in traditions that stretched from Confucian temples to Tibetan monasteries.

When the Eight Outer Temples and the Chengde Mountain Resort underwent extensive renovations beginning in 1979, workers used stone slabs quarried from local sites in Hebei. It was not until 1992 that researchers began noticing something unusual in the paving stones: fossilized tracks preserved in the rock. Subsequent investigation revealed over 40 dinosaur footprints at the Xumi Fushou Temple alone, embedded in stone slabs laid in front of the main entrance and behind the decorative paifang. The tracks date to the Jurassic-Cretaceous boundary, a geological transition some 150 million years ago when dinosaurs still dominated this landscape. Scientists have since documented similar tracks in stone used throughout Chengde's temple district, making this perhaps the only place in the world where Buddhist pilgrims and tourists routinely walk on dinosaur footprints without knowing it.

The Xumi Fushou Temple sits as one of Chengde's Eight Outer Temples, all of which were inscribed as UNESCO World Heritage Sites in 1994 alongside the Mountain Resort. But it carries a peculiar double significance that none of its siblings share. It is simultaneously a monument to 18th-century Qing diplomacy -- the physical evidence of a relationship between a Chinese emperor and a Tibetan spiritual leader -- and an accidental museum of deep geological time, its very foundations embedded with traces of a world that predates human civilization by more than a hundred million years. The Panchen Lama who preached here in 1780 stood on ground that dinosaurs had crossed in an era when the Yan Mountains were still taking shape. Whether you come for the golden rooftops or the ancient trackways, the temple rewards attention to what lies underfoot.
