Wine in a Cup from the Western Regions

He was a Silk Road merchant. He set out from Chang'an every year, carrying silk and tea, covering thousands of miles. Every time, his wife would see him off at the city gate, handing him a jug of wine and saying, "The wind blowing from thousands miles away in Chang'an will blow you back soon." That year he encountered a sandstorm and the entire caravan was wiped out. He crawled for three days and three nights before being rescued by a group of Hu merchants. The first thing he did when he woke up was to ask: "Is there any wind coming from Chang'an?" Hu Shang smiled. He continued walking on crutches for a whole year, and finally saw the city gate of Chang'an. At the city gate, the white-haired wife stood, still holding the pot of wine in her hand.
