Some said Zheng He was a comtemporary of Columbus. While Columbus went from Europe to America, Zheng He sailed from China to many places throughout South Pacific, Indian Ocean, Persian Gulf, and Africa (and possibly America) some 80 years before him.
A number of countries issued stamps to mark the 600th Anniversary of Zheng He's voyages.
First day cover & stamps here were designed and signed by Eng Siak Loy.
