Introduction to Xiangsheng Valley: It is opposite Yunwo across the stream. Because visitors can hear the echo when they call and laugh in front of the rock, it is also called "Sound Transmission in the Empty Valley". There are a dazzling array of inscriptions on the rocks in the valley. There are three inscriptions by Zhu Xi such as "The dead are like this", which is the essence of Wuyi Mountain cliff carvings.
