Where is Wu Zetian's palace?

Yes, at first, her palace was in Chang 'an, which is now Xi 'an. Later, it is said that after she brutally tortured and framed the queen and died, her heart was very uneasy, as if the ghost of Wang and Xiao were at work. In her dreams, the queen and the king often appeared with long hair, blood all over their faces and bared their teeth, which frightened her. First, it's impossible to move into Daming Palace. Nightmares still haunt her every day, making her tremble with fear. In order to avoid the ghosts of Wang and Xiao, Wu Zetian lived in Luoyang for a long time and moved the capital to Luoyang.
