An interpreter on the maritime missions
Ma Huan used the courtesy name Zongdao and signed himself the Woodcutter of Kuaiji. His preface states that in 1413 he joined a mission commanded by Zheng He because he could translate foreign texts. Liu Hong's later postface associates him with Guo Chongli, identifying both as Muslim interpreters who accompanied three voyages.
Interpreters worked at the meeting point between imperial missions and port communities. Communicating proclamations, negotiating transactions and understanding local descriptions required linguistic mediation. Ma's position produced a record concerned with markets and everyday practices as well as the ceremonial actions of the fleet.
Routes, commodities and transactions
In his preface Ma compares his earlier reading of Daoyi Zhi with what he encountered overseas. Yingya Shenglan arranges its information by place, including Champa, Java, Melaka, Sri Lanka, Calicut and Hormuz. Routes, currencies, weights, measures and products receive sustained attention.
The Calicut account describes negotiations involving officials, merchants, accountants and brokers. Parties recorded agreed prices in contracts before exchanging goods under those terms. These passages reveal the commercial procedures through which the fleet's textiles and ceramics entered established Indian Ocean markets, rather than portraying exchange as the delivery of gifts alone.
Compilation, circulation and the limits of the record
The surviving text preserves Ma's preface dated 1416, another by Ma Jing dated 1444 and a signature dated 1451, indicating continued compilation. Liu Hong also credits Guo Chongli with arranging printing so that the information could circulate more widely. The record was preserved through collaboration and successive textual transmission.
Ma includes legends, religious explanations and evaluations of unfamiliar customs. The section on Mecca, for example, describes seven interpreters being sent onward from Calicut on another vessel; that statement alone does not establish Ma's personal presence at every place described. Distinguishing eyewitness observation from reported information is essential to using the book's unusually detailed evidence.
