Palace of Union and Peace(Jiao Tai Dian)
This was the place where the empress held the important ceremonies for the New Year Day and her birthday.
In 1748, Emperor Qianlong kept 25 imperial seals in this hall in the hope of his empire lasting 25 reigns to surpass the East Zhou Dynasty, the longest dynasty in China. Now the 25 imperial seals are displayed in the Treasure House of the Forbidden City.
Additionally there is a water clock on the eastern side of the palace. It is China's most outstanding timepiece from ancient times.
On the western of the building there stands a large chiming clock. The clock was cast in 1798 over 200 years but is still in good working order.
Go to see the Hall of Terrestrial Tranquility ( Kunninggong) to have a look at what the spoiled emperors' wedding room looks like.
