What was the marriage process of ancient princes? Where is the emperor?

The whole country should put on holiday clothes and decorate with lanterns. The imperial palace should be paved with a red carpet, and the door gods and couplets will be completely new; Red lights should be hung at the palace gate and the temple gate of the meridian gate; Colored silk should be hung in the Double Happiness Gate, Hall of Supreme Harmony, Gan Qing Palace and Kunning Palace. On the day before the ceremony, the emperor sent officials to offer sacrifices to heaven, earth and ancestral temple respectively. On the day of the ceremony, there were festival cases, calligraphy cases and treasure cases in the hall of supreme harmony, and the emperor displayed a thin brine outside the hall. The emperor first went to Cining Palace to salute the Queen Mother, then went to the Hall of Supreme Harmony to study and see treasures, and then acceded to the throne. The ambassador and deputy ambassador took the wedding procession to the Queen's residence. This is basically the same as the ceremony of the Ming Dynasty.
