Ma Huan
During the 15th century, the Chinese Treasure voyages included an expedition to Sonargaon. The Chinese embassies to Bengal were part of the mission of Admiral Zheng He. The information about this expedition comes from the book of one of its participants, Ma Huan. In 1451, Ma Huan described Sonargaon as a fortified walled city, with a royal court, bazaars, bustling streets, water reservoirs, and a port.
