Soon after passing Luohan Rock, you will see some clay-filled buildings on the way to climb the mountain. The surrounding mountain walls are bare and there are no trees to hide. This is the fortification site of Taiping Army Building. It is said that this is the building left by the Taiping Army's young Wang Hongtiangui and the Ganwang Hongrenzong people near Luohanyan Mountains to block the Qing Army's 14-month stay.
