What is the Hall of Supreme Harmony in the Forbidden City for?

Nowadays, many people think that the Hall of Supreme Harmony is usually used to go to court, but it is not. The Hall of Supreme Harmony is actually a place where various ceremonies are held, and it is rarely used in fact. The places where the Ming and Qing emperors went to court were mainly Taihe Gate, Gan Qing Gate (for the Imperial Gate), Gan Qing Palace (where the emperor summoned ministers when there were important events or things) and hall of mental cultivation (for the late Qing Dynasty), which was not the usual Hall of Supreme Harmony. Twenty-four emperors of the Ming and Qing Dynasties held grand ceremonies in the Hall of Supreme Harmony, such as the emperor's accession to the throne, the emperor's wedding, the appointment of the queen, and ordering the expedition. In addition, every year, the emperor receives congratulations from officials of civil and military affairs and fetes princes and ministers. In the early Qing Dynasty, the Jinshi exam was also held in the Hall of Supreme Harmony. Since the fifty-fourth year of Qianlong (1789), it has been held in Baohe Hall, and Biography is still held in Taihe Hall. As for the position of the emperor's court, it is not in the Hall of Supreme Harmony. Throughout the Ming and Qing Dynasties, emperors usually appeared in court at Taihe Gate and Gan Qing Gate, saying that the imperial gate was in charge of politics. In the late Qing Dynasty, when there was an urgent or important matter, the emperor would call ministers in Gan Qing Palace, and Empress Dowager Cixi would listen to political opinions, so the seat of the court became hall of mental cultivation.
