We often say: It's better to take Wan Li Road than to study in thousands of books. There is such a strange man in history-Mr. Xu Xiake. Walking for more than 30 years, interacting with nature, and based on empirical evidence, he wrote Xu Xiake's Travel Notes with more than 600,000 words.

In this ancient book, which is known as the "ancient miracle", he took the foot as an oath, measured the famous mountains and rivers, and recorded his eternal love for the mountains and rivers of the motherland with a pen instead of a heart. He is not only a traveler, explorer, scientist, but also a writer. His travels always make people feel immersive.

When I was a teenager, I made up my mind that in this life, I must travel all over the three mountains and five mountains, travel all over Heyuan, learn geography and get married. My husband faces the blue sea at dusk, regardless of distance, regardless of dusk, regardless of mountains and seas, which is a heroic and ideal.

Xu Xiake walked the mountains and rivers all his life, constantly correcting many mistakes in the old records, and the feat of "Inspector Jiang Zhengyuan" was legendary in later generations. Xu Xiake was born in Jiangyin and grew up along the Yangtze River. He has always been interested in the source of the Yangtze River.

In his later years, Xu Xiake's southwest "Wan Li Expedition" took Wan Li as the last stop and failed to reach the source of the Yangtze River. When Xu Xiake followed Mr. Sa to Sanjiangyuan National Park, he tasted the water at the source of China Mother River, which fascinated him.

When Xu Xiake, who was in tears of joy, lamented "sweet, really sweet", Sa Beining paid heartfelt tribute to him on behalf of future generations: "Sir, you haven't finished the road, we have to move on!"

Teacher Meng Man said that Xu Xiake walked on the land of China all his life. The source of the Yangtze River he pursued was China, the famous mountains and rivers he traveled were China, and every place recorded in his travel notes was China. Xu Xiake's spirit of loving nature and pursuing truth is irreplaceable and indelible forever.

Over the past 300 years, generations of scholars have surveyed the earth and measured mountains and rivers, and the tools and means of research have changed with each passing day. But what remains unchanged is the spirit of seeking truth from facts and our love for the great rivers and mountains of the motherland. We should protect our green mountains and rivers and paint more magnificent mountains and rivers in the new era.
