The Qianqing Gate is the main court gate of the Forbidden City. Entering the Qianqing Gate, the emperor's concubines lived in the back palace. Ministers are not allowed to enter or leave this door at will, and enter the door of the Inner Court. There is a large stone carving opposite the gate, which reflects the wisdom, strength and hard work of the working people of China. It also reflects the luxury of the Royal family.
