Reading ten thousand books is not as good as traveling ten thousand miles. This sentence came from the Tang Dynasty poet Wang Zhihuan's poem "Climbing the Stork Tower". The whole sentence was: "The sun is against the mountains, the Yellow River flows into the sea." I want to see a thousand miles and climb another level. Once upon a time, people had already left this place by yellow crane, leaving the Yellow Crane Tower empty. The yellow crane is gone, never to return. Qingchuan calendar Hanyang trees, fragrant grass lush parrot island. Where is the village at dusk? The misty waves of the river make one sad." It meant that reading ten thousand books and traveling ten thousand miles were not contradictory but complementary. It was like climbing high and admiring the scenery of thousands of miles. Not only did one have to read thousands of books, but one also had to travel thousands of miles to understand the world more comprehensively. The poet used this sentence to express the importance of pursuing breadth and depth in knowledge and wisdom.
