I see. In the 23rd episode of TV series "Beauty of Tang Palace", Wu Meiniang learned the truth about the fake death of the heart and knew that the heart was still alive. Beauty in the Tang Palace tells the story of how Helan Xiner, a palace maid in Tang Gaozong's time, was promoted from the power struggle in the harem to a criminal prosecutor, and helped Empress Wu Zetian solve strange cases many times during this period.
