イブン・バットゥータ
Ibn Battuta described Urduja as the ruler of "Kaylukari" in the land of "Tawalisi" and leader of the "Kinalakian". After reaching the Samudra-Pasai Sultanate in what is now Sumatra, Indonesia, Ibn Battuta passed by Tawalisi on his way to China. Princess Urduja was described as a daughter of a ruler named Tawalisi of a land that was also called Tawalisi. The ruler of Tawalisi, according to Ibn Battuta, possessed many ships and was a rival of China, which was then ruled by a Mongol dynasty. Ibn Battuta sailed for 17 days to reach China from the land of Tawalisi.
