As soon as I saw this high-hanging "Taihe Temple", I knew how deeply Vietnam was affected by China. This imperial city of the Sui Dynasty is completely a small Forbidden City. The most interesting thing is the small emperor seat. It is said that the Sui Dynasty is still quite rich and prosperous. The emperor can completely change a tall dragon chair, but the emperor change chair is likely to be a bad sign of change, so don't change!! Then there is this small chair from beginning to end. Funny!
