First, low status.
In ancient Korea, some slaves obeyed the mother law, that is, the birth of a mother was the birth of a child. Although Zhang Lvshui is the daughter of the county magistrate, her mother was born an untouchable, because she is the lowest untouchable. As a result, Zhang Lvshui was sold to a brothel as a prostitute at an early age, learning to sing and dance. On one occasion, Zhang Lushui had the opportunity to meet Yan Shanjun, so he tried every means to seduce Yan Shanjun and was taken back to the palace by him. Zhang Lvshui, who should have been a pariah all her life, became the king's concubine, but her identity was still looked down upon.
Second, doing things savagely
Yan Shanjun's biological mother killed all the maids who were lucky enough to ascend to the throne at that time, and those who were caught bad at that time were executed. At that time, Yan Shanjun did not know the real cause of death of his mother. Zhang Lushui learned this by accident. In order to avenge those male and female servants who looked down on their origins, she revealed the cause of death to Yan Shanjun, which caused great disaster. Zhang Lvshui, who is still in love with Yan Shanjun, not only conspired with relatives to sell officials, but also took control of the state affairs. Whether it is a concubine or a former official, as long as they don't associate with her, they will be dismembered. They are very cruel people.
Third, help others abuse.
Yan Shanjun didn't like Buddhism, so Zhang Lvshui advised him to turn the temple into a brothel for fun. Yan Shanjun didn't like Confucianism, so Zhang Lvshui framed the literati and turned the school where the literati studied into a pub for people to drink and entertain. In addition, Zhang Lvshui also encouraged the Yanshan Army to expel residents within 30 miles of the capital and bring these places into the hunting circle.
