Zhou was part of an official delegation sent by Yuan Dynasty Temür Khan in 1296, although official Chinese records made no mention of his mission. On 20 February 1296, Zhou Daguan set sail from Mingzhou (明州, today's Ningbo) in Zhejiang province, on a compass guided ship, passing the ports of Fuzhou, Guangzhou, Quanzhou (Zaitong), the Island of Hainan, the Seven-Islands Sea (Qizhou yang), the sea off Central Vietnam coast (Jiaozhi Sea), and stopped over in Zhancheng or Champa (today's Qui Nhon). The ship resumed its trip past the province of Zhenpu (Bà Rịa in present-day southeastern Vietnam), through Poulo Condor Sea, then heading north on the Mekong River into Tonle Sap River reaching the town of Kampong Chhnang of Cambodia; from there he boarded a small boat, sailing for a dozen days, through Tonle Sap Lake arriving at Yaśodharapura (Angkor Thom), the capital of Cambodia in August.
