These fleets were a sight t behld and were in a league f their wn at that time. Under the cmmand f Zheng He, they set sail frm the Suth China Sea acrss the Indian Ocean t the muth f the Red Sea, and then t the east cast f Africa. African ryal families sent gifts such as giraffes as gestures f friendship in return fr gld, silk, and spices.
