The ancient city of Huizhou, known as the "Huizhou Tianzhu", has historically been known as the ancient city of Huizhou for its military fortress for having seven strong city gate buildings, and all the city gate buildings were destroyed more than 80 years ago due to war and other reasons. What is currently seen is the restoration and reconstruction of the Chaojingmen City Building in 2006 according to the original appearance of Huizhou Beichengmen in the Ming Dynasty.
