It had "Commandery Residences". Rafe de Crespigny, in Emperor Huan and Emperor Ling says about these "The Commandery Residences, which appear to have been grouped together in the eastern part of the walled city of Luoyang, were lodging houses maintained by the governments of commanderies and kingdoms for their messengers to the capital".
The Lodge of Tranquil Joy was in the suburbs west of Luoyang. Emperor Ling had held a grand review of troops there in the previous year, so it was evidently a sui table camping place for armies coming to the capital.
There were two imperial palaces at Luoyang, one in the north and one in the south of the city. These complexes were connected by the Covered Way, an elevated passage which led above the intervening area of the city so the ruler and his attendants could go from one to the other without a procession through the open streets.
The Gate of the Vermilion Bird was the main entrance to the Northern Palace, set in the southern wall and giving access to the city of Luoyang, and the tower of the gate was the tallest in the capital.
It had a Hall of Excellent Virtue.
It had a Palace of Perpetual Joy.
North there was a gate called Gu Gate, or Gumen Gate.
There was a Principal Gate, which was an interior gate of the Southern Palace, leading to the main audience halls.
