Zhan Hai is a writer about whom limited public information is available. The database currently holds one work by this author, The Amber Road. Classified under world history, the book is a work of historical writing whose title points to the ancient amber trade routes linking Eurasia and to the associated exchanges between civilizations, suggesting the author's interest in interregional trade, the movement of goods, and historical geography.
