"Baffled peasants in a windswept village in Gansu province are being described by Chinese newspapers as blond-haired, blue-eyed descendants of Roman mercenaries who allegedly fought the Han Chinese 2,000 years ago. While no one in the modern town of Lou Zhuangzi is fair and there is no proof that the Romans ever set foot in Gansu before the Christian era, the reports have revived discussion over whether a group of Romans offered their services to the Hun warlord Jzh Jzh in 36 B.C. before settling in the Gansu village of Liqian, thought by some to be Lou Zhuangzi."
One archaeologist I've read says that all Europeans have their origins in Gansu Province, China.
