Does the questioner want to ask "How to describe the scenery of Cangshan Mountain and Erhai Lake"? The green mountains are like paintings without ink for thousands of years; the green water is like a stringless harp forever. This poem was written by Lin Zexu to describe the green mountains of Cangshan in all seasons and the vast blue waves of Erhai Lake. It is included in "The Complete Works of Lin Zexu". Cangshan Erhai Lake is located in Dali, Yunnan, a national historical and cultural city that is well-known at home and abroad. It is one of the most beautiful places to check out the famous "Poetry and Distance", and it is also the ideal state in many people's minds.
