Which famous travelers entered China through Gansu along Silk Road routes?

The ancient Silk Road passed through the Hexi Corridor in Gansu, serving as the primary gateway for travelers entering China from the west. Notable figures who traveled these routes into China include:

• Marco Polo: The famous Venetian merchant traveled along the Silk Road in the 13th century, passing through Gansu (which he referred to as "Tangut") on his way to the Mongol court of Kublai Khan.123
• Kumarajiva: A renowned Buddhist missionary who entered China via the caravan routes that traversed the region.2

In addition to these individuals, the area around Dunhuang—a critical trading town in western Gansu—was a major point of entry for numerous Buddhist monks and missionaries arriving from Central Asia to spread their faith. The region's historical significance as a transit point is further evidenced by the Mogao Caves, which became a major center for pilgrimage and religious activity due to this influx of travelers.45
