Kaiyang castle was built in the Tang Dynasty. It belonged to Anyang City in the Warring States period. The whole castle is now planned on a turtle's back shaped like a "spirit turtle exploring water". The streets inside the castle are built according to the principle of "nine palaces and eight trigrams". Now the city walls, gates and streets are basically well preserved, but the buildings are incomplete. Only when they are paved on the ground from the gate hole, can we see the traffic and merchants in those days The prosperity of China.
