If you just stroll around, there are three halls on the central axis of the Forbidden City, as well as the cultural relics exhibition of the Hougong Pavilion, the Jubao Hall, the East and West Six Palaces and the Imperial Garden. There are Crystal Palace in Yan Xi Palace, as well as Palace of Gathered Elegance, Military Department and Changchun Palace, all of which are representative. The Forbidden City and the Cartier Jewelry Exhibition are all foreign palace products, which are feast your eyes. There is also the earliest telephone office in the Forbidden City, Puyi's Museum of the Combination of Chinese and Western, and the slant halls on both sides. The exhibits are worth seeing, ranging from jade boxes that Master Qianlong always plays with, precious old photos, to tea, perfume and medicinal materials. I hope this helps.

I said it wasn't enough, but I had to see it myself and experience it myself.
