Introduction to Guandi Temple: Zhangbi is located in the southeast of Jiexiu Basin, in a steep area with ravines on three sides and a plain on one side. Because there is a city wall outside the village, it is also called Zhangbi Castle. Don't underestimate this village. It was built in 619 AD for Liu Wuzhou's fight against Li Shimin in the late Sui Dynasty. The castle wall is 1,300 meters long. Every family in the village is connected and criss-crossed. There are also more than 10,000 meters of underground structures, which have been proven to be 1,300 meters tall. An ancient tunnel with three levels of history, both offensive and defensive. On both sides of the "Longji Street" built with red stones in the fort, temple complexes such as the Khan Temple, King Kong's Palace, Zhenwu Temple, Three Great Scholars' Hall, and Lu Zu Temple were built in an orderly manner, north and south of the village entrance. There are also Guandi Temple and Erlang Temple. It is a relatively complete ancient pocket "castle" in my country that integrates military, residential, production and religious activities and has many cultural relics and rare cultural relics.
