"Shuang Fei Lu" tells the story of a modern urban woman Lin Feifei (28 years old) who was transported to the fictional dynasty "Wei Dynasty" due to a car accident and was reborn as a girl (16 years old) with the same name. The original owner was poisoned by her aunt because she refused to marry the 63-year-old emperor. She and her sister Lin Yi were sent to the palace for a draft. Her sister was named a talented person, but she only got the "accepted" position. With modern wisdom and clear will, Lin Feifei worked her way up in the harem step by step. Through her medical skills, talents and strategies, she grew from a humble palace maid to the emperor's favorite concubine, holding the phoenix seal and assisting in the affairs of the court. She promoted the imperial examination for women, abolished the burial system, founded a private school for women, reformed palace regulations, and set off a storm of thought. She and her sister moved from estrangement to co-governance, and wrote the legend of "two stars shining together".
