Zhang Che, a student at the Imperial Acadmy of the Eastern Han Dynasty, was exiled from the border because of the Disasters of Partisan Prohibitions. After fleeing to the Western Regions, he married Sugisae, Queen of Supiye, without parents’approval. Later, Zhang Che followed Dhamadho, a person from Yuezhi, to Kushan. He learnt Kharosthi from Kushan and brought this writing back to Kroraina. Meanwhile, he tried to persuade Tomgraka, King of Kroraina, to accept refugees from Kushan. However, Kroraina and Supiye were enemies. In the end, Zhang Che made a difficult choice between rescuing his wife and helping the refugees. Dhamadho and other Kushan refugees fled to the Han Dynasty.
