Another important point: Zheng was a Muslim whose parents came from Xinjiang, and he had plenty of experience with Arabs. He was accompanied on his expeditions by Arab navigators, so there was nothing peculiar in the fact that he sailed his ships as far as Africa.
另外有一點，鄭和的父母來自新疆，他本身是伊斯蘭教徒（當時在南中國十分盛行的宗教），平日與阿拉伯人往來密切，下西洋時，船上甚至有阿拉伯人隨行，由他們出任重要導航工作，所以，他帶領的船隻會遠行至非洲，應不足為奇。
