徐霞客遊記
"徐霞客遊記" by Hongzu Xu is a Chinese travelogue written in the 17th century. Over 34 years, Ming dynasty geographer Xu Xiake traveled across all 16 provinces of China, documenting his journeys in more than 600,000 words. The work offers detailed observations of geography, hydrology, geology, and plant life while correcting geographical errors. Xu's dangerous travels and unwavering dedication inspired the phrase "spirit of Xu Xiake," celebrating his remarkable persistence and contributions to both science and literature.
