This day, 11 July, in 1405, Zheng He set sail from Nanjing on the first of seven voyages that would go as far as Africa. These southwestward voyages raised the international reputation of the Ming Dynasty, broadened the horizons of the Chinese people, developed navigation technology, opened up the Indian Ocean and the South China Sea, and made great contributions to international trade.
这一天，即1405年7月11日，郑和从南京启航，这是远至非洲的七次航行中的第一次。 这些西南航行提高了明朝的国际声誉，拓宽了中国人民的视野，发展了航海技术，开辟了印度洋和南海，并为国际贸易做出了巨大贡献。
