Literature Reference: The beauty of mountains and rivers has been a common topic since ancient times. High peaks pierce the clouds, and clear streams reveal their bottoms. Stone walls on both banks shimmer in five colors. Green forests and emerald bamboo are present in all seasons. At dawn, the mist begins to dissipate, and monkeys and birds chirp wildly; as the sun sets, fish leap in the water. It is truly a heavenly realm in the mortal world. Since the time of Kang Le, no one has been able to match its wonder. Source from 'Reply to Xie Zhongshu'.
