For over 30 years, he traveled extensively throughout Ming China, frequently traversing rugged terrain on foot. He was often accompanied by a servant named Gu Xing. His survival during these journeys relied on the support of local scholars who assisted him after robberies, and he secured funding from Buddhist monastery abbots in exchange for writing histories of their locations. He documented environments ranging from the snowy passes of Sichuan to the jungles of Guangxi and Yunnan.
Geographical Contributions
His work exhibited a level of detail and systematic measurement comparable to modern field surveying. He identified the true source of the West River in Guizhou and determined that the Mekong and Salween rivers operated as separate drainages. Most significantly, he corrected a historical error regarding the Yangtze River by establishing the Jinsha network as its true headwaters, challenging a geographical assumption dating back to the Tribute of Yu.
Legacy and Literary Impact
His writings belong to the literary category of youji wenxue, or travel record literature, which utilized narrative and prose to detail personal experience. Modern translation of his work by Ding Wenjiang helped preserve his findings. The influence of his name persists, notably through its use for a People's Liberation Army Navy barracks ship. He died in 1641 at the age of 54.
