In 221 BC, Qin Shi Huang unified China through ruthless conquest, but his paranoia birthed a deadly legacy
You are an imperial court scholar, tasked by Emperor Kangxi in 1699 to lift a curse threatening the Qing dynasty.
Your quest begins at Yongning Gate, the main access point to Xi
Thwart the ancient curse hanging over the Mausoleum of Qin Shi Huang, China's First Emperor, through Xi'an's millennia-old alleys.
« Chang'an, capital of emperors since antiquity »— Historic motto of Xi'an
Your journey begins at Yongning Gate, the main entrance to Xi'an's City Walls, which encircle the historic city center. These fortifications, with a total length of 13.74 km and a height of 12 meters, were entirely rebuilt under the Ming dynasty, particularly between 1374 and 1378, on Tang dynasty foundations. As a scholar, you examine the wall inscriptions, searching for the first clues of the curse. Xi'an's historic motto, "长安自古帝王都" (Chang'an, capital of emperors since antiquity), resonates as you imagine emperors entering and exiting this fortress, whose massive walls attest to its central role on the Silk Road.
Heading towards the heart of Xi'an, you reach the Bell Tower, built in 1384 under the Ming dynasty. This 36-meter-high square structure is the intersection of the city's four main avenues. The sound of its original 63.5-ton bronze bell could be heard 25 km away, according to Ming records. Just 350 meters to the west stands the Drum Tower, erected in 1380, which housed a giant drum used to mark hours and military alerts. These two towers, restored several times (notably in 1556 and 1739 for the Bell, and 1699 and 1996 for the Drum), are essential temporal markers, guiding you through the layers of Shaanxi's history.
Your investigation then leads you to the Forest of Steles, a museum founded in 1090 under the Song dynasty, and established in its current location in 1522. This site houses over 3,000 steles and 1,000 engraved stones, covering 2,000 years of Chinese history, from the 2nd to the 20th century. Among these treasures, some steles date back to the Tang dynasty (618-907), featuring calligraphic works by emperors and literati. Directly adjacent to this museum, Shuyuanmen Street, a 550-meter-long historic street dating from the Tang dynasty and restructured under the Ming, is famous for its ancient bookstores and calligraphy workshops. You search for clues in ancient writings, hoping to find the key to the curse.
The route then takes you to Daming Palace Park, an imperial palace built in 634 by Emperor Taizong of the Tang dynasty. Although abandoned in the 10th century and reconstituted as an archaeological park in 2010, its remains, such as those of Hanyuan Hall, attest to an original area of 3.2 km², larger than the Palace of Versailles. This site, 2.5 km northeast of Yongning Gate, represents the past splendor of Xi'an, a historical capital of the Silk Road. You explore the foundations of the buildings, looking for the repercussions of the First Emperor's curse on subsequent dynasties.
Your quest concludes with the analysis of the gathered information. You have explored the Ming City Walls, the Bell and Drum Towers, the Forest of Steles, and Daming Palace Park, all historic monuments of Shaanxi. Thanks to this interactive visit of Xi'an, you have not only retraced the city's history but also collected the necessary elements to lift the curse. The Mausoleum of Emperor Qin, located 35 km east of Xi'an, with its Terracotta Army, a UNESCO World Heritage site since 1987, remains the heart of this enigma, and you carry with you the satisfaction of having unraveled the secrets of the First Emperor's legacy.
