How did Shangguan Waner change from handmaiden to female prime minister step by step?

Like other people who have reached the peak of power, Shangguan Waner has a tragic and humble background. Because of grandpa Shangguan Yi's political wrong line, in 664 AD, his family was convicted-kill! Many relatives have lost their heads, including Shangguan Waner's father. At that time, the poor little boy had just been born, and before he ate a few mouthfuls of milk, he became a "servant" of the court with his mother Zheng. Although I was lucky enough to save my life, my situation was extremely low. The mother worked hard and stumbled to pull her little daughter. Of course, the declining butler is also very learned, and his mother tried every means to let Wan'er receive a comprehensive and strict orthodox education-this is the capital to settle down in the future. The little girl is too clever to know anything. He wrote a beautiful poem when he was only four or five years old.

Old Tang Shu told a half-truth story in biographies:

During Zheng's pregnancy, she dreamed that a giant sent a steelyard and said, "Take this and weigh it!" "What a big breath! Weighing the world is not the character who has the final say around the emperor! Probably, to have a son. Unexpectedly, a chubby white baby girl was born-disappointment. Dreaming can only be a fake smile.

Wu Zetian finally gave the ruined Shangguan family a chance to turn over and be liberated. She had heard about Shangguan Waner's talent for a long time, so she called the poor mother and daughter into the palace. On-the-spot investigation-I was very satisfied, so in addition to the "cheap record" of their mother and daughter, I left Wan'er and worked everywhere as my personal secretary in charge of the imperial edict. That year, Shangguan Waner was just 14 years old. From then on, she set foot in politics and approached the power core of the dynasty step by step.
