（原文）
wnauy徐霞客一生周遊考察了16個省，足跡幾乎遍及全國。他在考察的過程中，從來不盲目迷信書本上的結論。他發現前人研究地理的記載有許多不很可靠的地方。爲了進行真實細緻的`考察，他很少乘車坐船，幾乎全靠雙腳翻山越嶺，長途跋涉;爲了弄清大自然的真相，他總是挑選道路艱險的山區，人煙稀少的森林進行考察，發現了許多奇山秀景;他常常選擇不同的時間和季節，多次重遊各地名山，反覆觀察變換的奇景。

During his lifetime, Xu Xiake traveled around and conducted surveys in 16 provinces. He left his footsteps in virtually every part of the country. In the process of conducting his surveys and investigations, he would never blindly embrace the conclusions recorded in previous documents. Instead, he discovered that the documentations made by his predecessors in their geographical studies were not quite reliable in many aspects.
In order to ensure that his reconnaissance were real and detailed, he seldom traveled by ship or by wagon. He climbed over mountains and hills and traveled long distances almost entirely on foot. In order to develop a true picture of the natural world, he made it a point of undertaking his expeditions in those mountain areas where roads were difficult to travel and in those woods that were sparsely populated. In this way he discovered many marvelous mountains and beautiful scenes. He frequently chose different times and seasons of the year to make repeated visits to the famous mountains across the country so that he could make repeated observations of their wonderful scenery that kept changing all year round.
