Within the main hall of the palace stands the imperial throne, above which hangs a plaque inscribed with the phrase "Cheng Ming Guang Ming" means  “Upright and Just" penned by Emperor Shunzhi. This idiom conveys that one's actions should be upright, honest, and in accordance with established norms.

 

Behind the throne is a seven-paneled golden screen intricately carved with dragons playing with pearls. Red candles and a pair of large mirrors are positioned on either side of the throne to ward off evil spirits. Two pairs of couplets, authored by Qing emperors, adorn the columns. The Palace of Heavenly Purity is notably spacious, divided into two sections, each comprising nine rooms and 27 beds. Each night, the emperor would randomly select a bed to rest on, a design implemented during the Ming Dynasty to thwart assassins by preventing them from determining the emperor's sleeping location.
