Short drama actor Zhao Wei was originally a small actor who made a living by imitating various characters. In a filming accident, he traveled back to the Zhou Dynasty and became the "stand-in" for the seriously ill emperor. The undercurrent in the court is turbulent, and the harem is frightening every step of the way. He must use his acting skills to deceive the civil and military officials of the court, and survive in the crisis-ridden palace. If the performance is good, he is a nine-five-year-old; if the performance is bad, he will be doomed. This is an actor who interprets the story of an emperor's life on a real historical stage.
