So far we had transited Tiananmen Square and walked around the Hall of Supreme Harmony before entering the inner courtyards of the Old Palaces (Forbidden City)..

Along the way I learned that the height of a building’s threshold denoted the status of the resident. The higher the resident’s status, the higher his threshold. Threshold height had a more practical role too. High thresholds kept flood waters, cold air, and crawling critters from easily entering the building.
	Next we used the interlocking courtyards to reach the Hall of Consolation, also known as “where the Emperor goes to play”.

During the age of the Dynasties Manchurian women (girls) ages 13 to 17 were automatically engaged to the royal family, with the understanding that they might be drafted to be the Emperor’s concubine. If not selected by the age of 18 the women were free to have boyfriends or get married. A collection of small rooms or bays in the Hall of Consolation served as housing for the Emperor's many concubines. The Old Palaces were guarded and served by eunuchs. These castrated men were trusted to be guardians and servants of the Emperor's concubines. Th eunuchs, more or less, had free reign to travel about the Forbidden City. One Emperor, his name is missing in my notes, had more than 100,000 eunuchs handling the domestic affairs of the Imperial City.

The Emperor traveled through the Imperial Gardens when he left his residence to go anywhere else in the Imperial city.	Cypress trees in the Imperal Garden were older than the Forbidden City itself.
