简介： Centuries before the world's oceans became a global trade highway, Chinese seafarers set sail to faraway lands to exchange commodities. Now, Historian Sam Willis retraces the golden era of maritime trade to uncover a legacy that culminated in one of the greatest armadas of all time, and discover parallels between the world then and now.
