The main decoration of the Hall of Supreme Harmony is the dragon. These dragons are distributed in every corner of the Hall of Supreme Harmony. For example, the furnishings on both sides of the emperor's throne, including treasures, heads, cranes and champs, are decorated with exquisite dragon patterns. The dragon is the embodiment of the emperor, who pretends to be the "real dragon son of heaven". The dragon is also a symbol of imperial power, and the majesty of imperial power is prominent.
