Hongyu Mountain Villa Great Wall Park is at the foot of Yanshan Mountain, at the bottom of the Great Wall, north of Hongyukou Village in Qian'an City. The natural landscape here is magnificent. According to history and popular legends, the Tang Emperor occupied the East, the Qin Emperor built the city and Qi Emperor guarded the frontier, adding a touch of mystery to the atmosphere. Hongyu Kou was the battleground of dynasties. During the Second Sino-Japanese War, Japan attacked Hongyu Kou and the rebellion of the local people is widely remembered. The stalactites, stalagmites and stone flowers in the cave have widely varying shapes. Looking out from the mouth of the cave, the 4000 stone steps, such as the sky ladder, all look spectacular. Five-layer halls were delicately built, and the statues in the temple are equally exquisitely crafted.
