Our guide explained how the Emperor lived like a god on earth, being carried around on a palanquin, and resting from the business of empire in a tented area inside his part of the palace, a splendid 15 roomed building which was for his sole use. His family lived in separate buildings within the walled palace grounds.
Showing us a map of the Palace, our guide pointed out that the North East is considered an unlucky direction for the Imperial palace, so there is a symbolic guardian monkey placed under the roof on that corner of the building. The monkey is encased in wire gauze. This is because the monkey may do evil to passersby at night, making it necessary to confine it. Additionally, the north east corner of the palace walls is cut away as an added protection.
Perhaps, I need a monkey to occupy the north east corner of my desk, watching over my Mac, when it returns from the menders.
