Empress Wu Zetian (played by Gui Yalei) of the Tang Dynasty was unable to give birth after being pregnant for 12 months. It was raining heavily, and when the good news of the victory over the Turks came, Wu Zetian's amniotic fluid broke. The princess came into the world in the wind and rain. Emperor Gaozong of Tang, Li Zhi, believed that the birth of his daughter would bring good luck to the world, and named her Princess Taiping on the spot. The young Taiping (played by Zhou Xun) was naughty and teased her three brothers, piercing the little love between her good sister Wei (played by Hu Jing) and her brother Xian, but also witnessed the storms of the struggle in the palace. But these storms were still far away from Taiping. It was not until she was 16 years old that she secretly left the palace with Wei and met Xue Shao (played by Zhao Wenxuan) in the hustle and bustle of the night market that the girl fell in love. Under Taiping's petition, Wu Zetian agreed to Taiping's marriage request even though she knew that Xue Shao already had a wife. She arranged the death of Xue Shao's wife Hui Niang, which also laid the groundwork for Taiping's marriage tragedy. After marriage, no matter how gentle and considerate Taiping was, Xue Shao never said a word. However, Taiping (played by Chen Hong), who was stubborn and desperate for love, won the trust of the Xue family. When the truth was ruthlessly revealed, the only request of the Xue family to her was to keep the Xue family's bloodline - Ye'er. Xue Shao's death brought great trauma to Taiping and also tore an unbridgeable crack in the relationship between mother and daughter. Wu Zetian ascended the throne and founded the Great Zhou Dynasty. Taiping married Wu Yousi (played by Fu Biao), who was honest but had no skills, in order to be angry with her mother. She spent five long years of joyless marriage. But this period cultivated Taiping's political ability. She solved political crises for her mother again and again, and was deeply valued by Wu Zetian. However, she still refused to enter politics. Wu Yousi, who loved Taiping deeply but suffered from not being able to get Taiping's heart, had a secret affair after drinking. After being caught by Taiping, he committed suicide out of shame. Taiping ended her second marriage in this way. When Zhang Yizhi (played by Zhao Wenxuan), who looks very similar to Xue Shao, appears in front of Taiping, Taiping's heart is arrested again. However, during the relationship, she realized that Zhang Yizhi is definitely not Xue Shao. They are only entangled in lust, and Zhang Yizhi is eager to control the world by controlling women. Zhang Yizhi not only has an affair with Taiping, but also has a relationship with Wei and Wu Zetian, which deeply hurts Taiping's heart. When Zhang Yizhi attempted to usurp the throne, Taiping, who came from afar, ended his life with a knife and cut off her love. Wu Zetian died and Taiping became the Princess of Zhenguo. Nephew Li Longji took good care of her, and Ye'er at that time also grew up to be a tall and good young man, and was a close friend of Li Longji. These two young people love Taiping in their own way: Li Longji loves her to let his aunt get the power of the world, and Ye'er loves her to let Taiping leave the power dispute. This contradiction is on the verge of breaking out...
