Fengtian Hall(Hall of SupremeHarmony) ,located at the core of the north-south axis of Nanjing Palace Museum, China, is on the top of the hall with double eaves, sitting on three steps of the Han Dynasty, nine wide and five deep. In the early years of the Ming Dynasty, the three Dynasties of Hongwu, Jianwen and Yongle held important ceremonies and received congratulations from officials. The left side of Fengtian Hall is the middle left door, and the right side is the middle right door (I didn't actually draw these two doors, because it would destroy the beauty of the building).
