The Accounts of China and India, covering the trade between the Persian Gulf and points east in the 9th and 10th centuries, and the writings of Abu Zayd al-Sirafi. There are cultural customs, trading routes, and the calamitous events of the late 9th-century that shattered that trade and the Tang Dynasty.
