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 depths. The stone walls on both banks radiate with five colors; the green forests and emerald bamboo are present in all four seasons. As the morning mist dissipates, monkeys and birds sing in chaos; as the sun sets, fish leap in competition. Truly, it is a fairyland in the mortal world. Since the time of Kang Le, none have been able to match its wonder. Source from 'Lantingji Xu'.
