Wang Dayuan
Andaya and Andaya write that Dao Yi Zhi Lue provides more information on areas east of the Malay Peninsula than any other Yuan dynasty source. According to the postscript Wang Dayuan visited all the places described. However, Park notes that 90% of the text is devoted to Southeast Asia and that Wang does not give details of his route and itinerary to West Asia. However, Deng states that Wang Dayuan's account is consistent with later Ming Dynasty accounts of Zheng He's travels. There is currently no English translation of the book but the Chinese version can be read with the NTI Reader. Partial translations however are available.
