Loulan or Kroran is an ancient oasis town already known in the second century BCE on the north-eastern edge of the Lop Desert. Loulan, known to Russian archaeologists as Krorayina, was an ancient kingdom along the Silk Road. In 77 BCE, according to the History of the Former Han Dynasty, the Chinese envoy Fu Jiezi stabbed Loulan’s king, Chang Gui, to death. The kingdom then became a Chinese puppet state and was given the Chinese name of Shanshan, though the town at the northwestern corner of the brackish desert lake Lop Nur retained the name of Loulan. The ruins of the town of Loulan are on what were the western banks of Lop Nur, now dessicated, in the Bayin’gholin Mongol Autonomous Prefecture, Xinjiang. The site is now completely submerged in the desert.
